Question 1

A technician puts 20.0 cm3 of 0.120 mol/dm3 sodium hydroxide solution into a conical flask. The burette contains 0.0800 mol/dm3 sulfuric acid.

2NaOH+H2SO4→Na2SO4+2H2O2\text{NaOH} + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O}2NaOH+H2​SO4​→Na2​SO4​+2H2​O

What titre of sulfuric acid should the technician expect at the end point?
