A student carried out a titration to find the concentration of a sodium hydroxide solution.
18.50 cm3 of dilute sulfuric acid with a concentration of 0.100 mol dm-3 reacted completely with 25.00 cm3 of the sodium hydroxide solution.
H2SO4+2NaOH→Na2SO4+2H2O \text{H}_2\text{SO}_4 + 2\text{NaOH} \rightarrow \text{Na}_2\text{SO}_4 + 2\text{H}_2\text{O} H2SO4+2NaOH→Na2SO4+2H2OCalculate the concentration of this sodium hydroxide solution.
