A 0.50 mol/L sodium carbonate standard was used to determine the concentration of a hydrochloric acid solution. A 25 mL sample of the standard required 21.06 mL of hydrochloric acid for complete neutralisation. Calculate the concentration of hydrochloric acid.
A 5.00 mL sample of commercial vinegar wascompletely neutralised by 24.50 mL of 0.150 mol/L NaOH solution. Calculate the ethanoic acid concentration of the vinegar.
What volume of hydrogen gas would be produced at standard temperature and pressure (S.T.P.) by reacting 50.0 g of aluminium with hydrochlorci acid?
When 25 mL of 0.0858 mol/L sodium carbonate solution was titrated with a solution of hydrochloric acid, the volume of th acid needed to reach the equivalence point was 37.8 mL. Find the concentration of the hydrochloric acid solution.
