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-.
We use the hydronium ion as the more logical way a hydrogen ion appears in an aqueous solution, although in many chemical reactions H and H 3 O are treated equivalently. The reaction of an acid and a base is called a neutralization reactionThe reaction of an acid with a base to produce water and a salt. .Although acids and bases have their own unique chemistries, the acid and base cancel each otherâs chemistry to produce a rather innocuous substanceâwater.e use the hydronium ion as the more logical way a hydrogen ion appears in an aqueous solution, although in many chemical reactions H and H 3 O are treated equivalently.
