Show all calculations for full value. Include a dissociation equation for each weak acid or weak base with water and ICE tables for all questions. If the quadratic equation applies, use technology $($Wolfram Alpha$)$ to solve state this and give both values of $"x"OR$ if the Approximation Method applies justify with a calculation.

Only the first dissociation : ex $H_{2}S{O}_4+H_{2}O{H}_3{O}^{+}+HS{O}_4^{-}$if there is more than $1$ hydrogen....

NO SALTS HERE $!!!$

Given a solution of Lactic acid, whose formula is $H{C}_3{H}_5{O}_3,$ write a dissociation equation for this acid water. If the concentration of this acid is $0\mathrm{.}626mo\frac{l}{L}$ and the accepted acid dissociation constant, $K_a,$ is $1\mathrm{.}410-4,$ calculate the $pH$ of this solution. In addition, calculate the percent dissociation of this acid. $(8)$

Calculate the acid dissociation constant for Formic acid, $HCH{O}_2$ with a concentration of $0\mathrm{.}164mo\frac{l}{L}$ and a measured $pH$ of $2\mathrm{.}25.(6)$

Weak bases such as morphine, $C_{17}{H}_{19}{O}_{3}N,$ show very little dissociation. Write a dissociation equation for this base. A solution of morphine is prepared by dissolving $2\mathrm{.}82g$ to a volume of $546mL-$ the base dissociation constant, $K_b$ value, is $7\mathrm{.}4{10}^{-7}-$ calculate the $pH$ of this weak base. $(8)$
