Men's hats are sized according to diameter while women's are based on circumference. The most common hat size for men is 7 1/8 and for women, 221. To measure the size of a person's head, use a flexible tape measure to measure the circumference at the widest part of the head, usually an inch above the eyebrows.
Arrhenius argued that bases are neutral compounds that either dissociate or ionize in water to give OH-ions and a positive ion. NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH -) and sodium (Na +) ions.
Acids and bases neutralize each other. This is pretty obvious, as you probably know an acid donates H+ ions, while bases accepted them. An reaction between an acid and base w â¦ ould produce the salt of the two.Sulfuric acid produces sulfate salts, nitric acid produces nitrite salts, hydrochloric acid produces chloride salts, etc.n acid is a sour substance which has Hydrogen (H^+) ions in it. A base on the other hand is bitter and has Hydroxide (OH^-) ions in it. 18 people found this useful.
