Calculate the pH of a 0.045 M HOCl solution. {eq}(K_a = 3.5 \times 10^{-8}) {/eq}Weak Acids:A weak acid is characterized by its partial dissociation in solution. We can assess the relative strengths of weak acids by using its acid dissociation constant. The acid dissocia...
The sour taste and smell of vinegar is due to the acetic acid present in solution. The active component is a weak acid known as acetic acid. It acts as a weak acid according to the chemical equation below. An equilibrium eventually forms between the ions and the unionized ...

Calculate the pH of a 0.0190 M solution of H2S. Weak Diprotic Acid:A monoprotic Arrhenius acid has a single dissociation equilibrium in aqueous solution, whose strength is described by a dissociation constant Ka. If Ka<1, then the step is relatively weak, and the equilibrium state will be ...
A buffer is an aqueous solution designed to maintain a constant pH, even when exposed to small amounts of acids or bases. Whether acidic (pH < 7) or basic (pH > 7), a buffer solution consists of a weak acid or base mixed with the salt of its conjugate ba

Buffer solution des not mean that there does not occur a pH change at all. It implies the pH change occurs but in neglibible amount. There are two types of buffer (i) Acidic buffer: it is a mixture of weak acid and its salt acid strong base. (ii) Basic buffer : It is a ...
