Why does demineralization of hydroxyapatite occur faster when in a solution of hydrochloric acid compared to acetic acid? Make sure to use the demineralization equation for hydroxyapatite to explain your answer (Use the generalized demineralization equation with H+ representing the acid)

Ca5(PO4)3OH + H+ --> 5Ca2+ + 3PO43- +H2O

You need a strong acid for an experiment, and you are given a bottle that you are told contains a strong acid at 15.0 M concentration. (The name of the acid on the label was rubbed off, so you are not sure of the identity of the acid.) You make a 0.1 M solution and you want to know if you can assume that the [H+] will be 0.1 M since the acid is a strong acid and thus should...

When a solution contains a weak acid and its conjugate base or a weak base and its conjugate acid, it will be a buffer solution. Buffers resist change in pH following the addition of acid or base. A buffer solution prepared from a weak acid (HA) and its conjugate base (A−) is represented as HA(aq)⇌H+(aq)+A−(aq) The buffer will follow Le Châtelier's principle. If acid is added, the reaction shifts to consume the added H+, forming more HA. When base is...
