Since vitamin C compound is a prominent component of most fruits and vegetables, we easily ingest the daily $0\mathrm{.}05$ grams required for the prevention of scurvy. Many people believe that a large dose of vitamin C prevents colds, although this view is not supported by a firm body of clinical evidence.

If $500$mg tablet of vitamin C is dissolved in $50\mathrm{.}0$ mL water at $25$ oC to make a solution, answer the following questions:

a$.$ Calculate the molar mass and concentration of ascorbic acid. $(2$ marks$)$

b$.$ Write the equilibrium reaction, the equilibrium expression, and calculate the equilibrium concentrations of all chemical species. $(8$ marks$)$

c$.$ What is the pH and percent ionization of this solution? $(2$ marks$)$

d$.$ Calculate the acid ionization constant $($Ka$)$ and the pKa. of Vit C $(2$ marks$)$

e$.$ What are the values of Kb and pKb for the ascorbate ion? $(2$ marks$)$

PLEASE ANSWER CORRECTLY WITH PROPER UNITS AND NOTATIONS FOR EQUILIBRIUM ETC AND BE AS DETAILED AS POSSIBLE THANK YOU
