The list of deleterious materials has always remained fluid because as technology advances new products come onto the market and medical research establishes new risks to health. Clauses in contracts and appointment documents often refer to compliance with 'Good Practice in the selection of construction materials'.he list of deleterious materials has always remained fluid because as technology advances new products come onto the market and medical research establishes new risks to health.

Hydrogen peroxide is a weak acid. Generally, acids distinguishable by the hydrogen proton, while bases are generally anything with a hydroxide. For instance, hydrochloric acid, or HCl, can be distinguished by the H+ bonded with Cl-. NaOH on the other hand, is a bond between Na+ and OH-.
Top. Calculation of the pH of a Buffer Solution after Addition of a Small Amount of Strong Base. When a strong base (OH -) is added to a buffer solution, the hydroxide ions are consumed by the weak acid forming water and the weaker conjugate base of the acid.The amount of the weak acid decreases while the amount of the conjugate base increases.op.
