Nitric acid, HNO3(aq)\text{HNO}_3\text{(aq)}HNO3(aq), is a strong acid, whereas ethanoic acid, CH3COOH(aq)\text{CH}_3\text{COOH(aq)}CH3COOH(aq), is a weak acid.
Explain the difference between a strong acid and a weak acid in terms of ionisation.
Acidic solutions contain hydrogen ions, H+\text{H}^+H+. Alkaline solutions contain hydroxide ions, OH−\text{OH}^-OH−. Write the balanced ionic equation for neutralisation.
A student investigates the neutralisation of sodium hydroxide, NaOH\text{NaOH}NaOH, with nitric acid, HNO3\text{HNO}_3HNO3.
Write a balanced symbol equation for this reaction.
Describe how a dry, pure sample of sodium nitrate crystals can be obtained from the neutralised solution.
Nitric acid is a strong acid.
A student has a solution of nitric acid with a pH of 2.0. They add water to dilute the solution until the concentration of hydrogen ions decreases by a factor of 1000. Calculate the new pH of the solution.
