The chemist slowly added 0.05 mol / dm3 sodium hydroxide solution to 1.0 dm3 of acidic lake water contained in a beaker until the acid had just been neutralised The chemist found that it required 12.5 cm3 of 0.05 mol / dm3 sodium hydroxide solution to neutralise the acid

a. State the number of moles of sodium hydroxide which are dissolved in 1.0 dm3 of the sodium hydroxide solution

b. Calculate the number of moles of sodium hydroxide which are dissolved in 12.5 cm3 of the sodium hydroxide solution. Show your workings.
Show your working.

c. The balanced equation for the neutralisation reaction is
2NaOH + H2SO4 → Na2SO4 + 2H2O
Calculate the number of moles of sulfuric acid which were contained in 1.0 dm3 of acidic lake water.
