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.
