Preliminary Problems:

What property of a solution is described by its $pH?$

Acid$-$Base Property

A solution has a $pH9\mathrm{.}2.$

a$.$ Is this solution acidic, basic, or neutral?

Basic

b$.$ What is the concentration of the hydronium ion, $H_{3}O+?$

Solution A has a hydronium ion concentration of $4\mathrm{.}110-8M.$ Solution $B$ has a hydronium ion concentration of $1\mathrm{.}910-4M.$

a$.$ Which solution has the greater hydronium ion concentration?

b$.$ Which solution has the greater $pH?$

Estimate the $pH$ of an aqueous solution for each of the following compounds:

a$.HCl$

b$.$ NaCl

c$.N{H}_3$

d$.$ NaOH

e$.HN{O}_3$
