Question 10

A technician needs to exactly neutralise the barium hydroxide in 25.0 cm3 of 0.0200 mol/dm3 barium hydroxide solution. The hydrochloric acid available has a concentration of 3.65 g/dm3. Mr(HCl)=36.5M_r(\text{HCl}) = 36.5Mr​(HCl)=36.5. The equation for the reaction is:

Ba(OH)2+2HCl→BaCl2+2H2O\text{Ba(OH)}_2 + 2\text{HCl} \rightarrow \text{BaCl}_2 + 2\text{H}_2\text{O}Ba(OH)2​+2HCl→BaCl2​+2H2​O

What volume, in cm3\text{cm}^3cm3, of hydrochloric acid solution should the technician use? Show your working.
