What base is strong but never concentrated? 10 pts best answer? MgOH and NaOH are both strong bases but are often concentrated. Ammonia is a weak base. Water is amphoteric and so can act as an acid or a base (proton acceptor/donator) according to the bronsted lowry definition.It can therefore be a strong base depending on the reaction but is never concentrated as it is water.

Base (chemistry) Weak bases, such as baking soda or egg white, should be used to neutralize any acid spills. Neutralizing acid spills with strong bases, such as sodium hydroxide or potassium hydroxide can cause a violent exothermic reaction, and the base itself can cause just as much damage as the original acid spill.

What pH Levels Are Considered Strong & Weak? Strong Acids. Generally, a strong acid has a pH of about zero to 3. The stronger the acid, the better it dissociates in an aqueous solution, releasing more cationic hydrogen (H+) ions. Examples of strong acids include hydrochloric acid (HCl), hydrobromic acid (HBr), perchloric acid (HClO4), and sulfuric acid (H2SO4). However, because pH measures the amount of hydrogen ions released in a solution, even a very strong acid can have a high pH reading if its concentration is very dilute.

Acid strength The strength of an acid refers to its ability or tendency to lose a proton (H +). A strong acid is one that completely ionizes (dissociates) in a solution. In water, one mole of a strong acid HA dissolves yielding one mole of H + (as hydronium ion H 3 O +) and one mole of the conjugate base, A − .or concentrated solutions of strong acids with a pH less than about zero, the Hammett acidity function is a better measure of acidity than the pH. Sulfonic acids, which are organic oxyacids, are a class of strong acids. A common example is p-toluenesulfonic acid (tosylic acid).

- One of the strongest acids, aqua regia, is made from a mixture of nitric and hydrochloric acids, and can dissolve most… metals. It has a pH value that approaches zero. The pH value of an acid solution depends on the acid concentration. The solutions with higher acid concentration have lower pH values and vice versa. 10 people found this useful.

What is the difference between a strong base and a weak base? On the other hand, weak based don't disassociate well in water (generally about less than 2% if I recall correctly). So the only huge difference is the degree at which the ionic compounds split apart. Strong=100% disassociation Weak=less than ~2%. This rule also applies to strong and weak acids.

- Sodium hydroxide is a strong base and will ionize completely in water. It is less acidic than water, so the water acts as an acid and donates a proton to form a hydroxide. Water is naturally neutral. Other things added to water may change it towards an acid or a base.

Strong Acids and Bases Strong Acids and Bases. Acids and bases that are completely ionized when dissolved in water are called strong acids and strong bases There are only a few strong acids and bases, and everyone should know their names and properties. These acids are often used in industry and everyday life. The concentrations of acids and bases are often expressed in terms of pH, and as an educated person, you should have the skill to convert concentrations into pH and pOH. The pH is an indication of the hydrogen ion concentration, [H + ].

- H2CO3 is a weak acid and its conjugate base must be a strong base, H2CO3 = H+(aq) + HCO3-(aq) Eq Constant value is too low the products will not dominate, the reaction has hardly proceded to forward direction. i.e HCO3- ion has great tendency to take up proton thus a strong base.trong acids/bases give rise to weak conjugate bases/acids Weak acids/bases give rise to strong conjugate bases/acids That's just because an equilibrium that is very much in favour of one is very much against the other. (Original post by jsmith6131). HCO3- is the strong conjugate base of H2CO3. HCO3- = CO3 2- + H+.

- Explaining the term strong base. A strong base is something like sodium hydroxide or potassium hydroxide which is fully ionic. You can think of the compound as being 100% split up into metal ions and hydroxide ions in solution. Each mole of sodium hydroxide dissolves to give a mole of hydroxide ions in solution.

- Never store mixtures of concentrated acids, particularly nitric acid, and organic or inorganic waste components; immediately dilute any mixtures generated from concentrated acids by slow addition to ice or water in an open plastic container or a plastic bottle behind a shield or hood sash.ncompatibilities of concentrated nitric acid: Never mix concentrated nitric acid and organics, such as acetone, unless you are following a respectable procedure and use a blast shield and proper precautions.

Acid strength Most acids are weak acids. A weak acid is an acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution. Thus, it is less capable than a strong acid at donating protons. These acids have higher pKa than strong acids, which release all of their hydrogen atoms when dissolved in water.or concentrated solutions of strong acids with a pH less than about zero, the Hammett acidity function is a better measure of acidity than the pH. Sulfonic acids, which are organic oxyacids, are a class of strong acids. A common example is p-toluenesulfonic acid (tosylic acid).

- Chemical Concept Demonstrated: Strengths of acids and their conjugate bases. Demonstration and Explanations: 1. Compare HCl, HOAc, NaCl, and NaOAc: HCl is a stronger acid than HOAc. NaCl is a weaker base than NaOAc. Stronger acids have weaker conjugate bases. 2. Compare HCl, NaOH, and NaCl: HCl is a stronger acid than water. NaCl is a weaker base than NaOH. Strong acids react with strong bases to form weaker acids and bases. 3. Compare NaOH, NH3, and H2O, and NH4Cl: NaOH is a stronger base than NH3. Water is a weaker acid than NH4Cl. Weaker bases have stronger conjugate acids. NH3 is a weak base, but its conjugate acid, NH4Cl, is a strong acid.

What is the difference between a strong and weak base? A weak base comes from a strong acid (when the acid loses a proton or accepts an electron pair). A strong base comes from a weak acid. Generally, acid strength increases with electronegativity and size. A weak base comes from a strong acid (when the acid loses a proton or accepts an electron pair).

- Estimation of pH - Strength vs. Concentration. Concentration refers the amount of acid or base present in a given amount of solution. A concentrated solution is one that contains a large amount of acid or base in a given volume. A dilute solution is one that contains a small amount of acid or base in a given volume.

- Weak Acids and Bases. Weak acids and bases are only partially ionized in their solutions, whereas strong acids and bases are completely ionized when dissolve in water. Some common weak acids and bases are given here. Furthermore, weak acids and bases are very common, and we encounter them often both in the academic problems and in everyday life. The ionization of weak acids and bases is a chemical equilibrium phenomenon. The equilibrium principles are essential for the understanding of equilibria of weak acids and weak bases.
