#### Q1.

Given the following reaction:

$H_2SO_4 + NaOH \rightarrow Na_2SO_4 + H_2O$

If it takes 27.4 mL of 0.768 M $$NaOH$$ to titrate 16.7 mL of $$H_2SO_4$$, what is the concentration of the $$H_2SO_4$$ solution? (hint: balance the equation first)

#### Q2.

Given the following reaction:

$NaOH + HCl \rightarrow H_2O + NaCl$

If 24.5 mL of $$HCl$$ solution is needed to titrate 33.0 mL of a 0.112 M $$NaOH$$, what is the concentration of the $$HCl$$ solution?

#### Q3.

Given the following reaction:

$Ba(OH)_2 + HClO_4 \rightarrow Ba(ClO_4)_2 + H_2O$

How many mL of 1.2 M $$HClO_4$$ is needed to neutralize 5.8 mL of a 0.44 M $$Ba(OH)_2$$ solution?

#### Q4.

Given the following reaction:

$H_2SO_4 + Na_2CO_3 \rightarrow Na_2SO_4 + H_2O + CO_2$

Calculate the molarity of the $$H_2SO_4$$ solution if it takes 40.0 mL of $$H_2SO_4$$ to neutralize 46.7 mL of a 0.364 M $$Na_2CO_3$$ solution.
