Write down the molecular formula of methanesulfonic acid.
Methanesulfonic acid is stronger than ethanoic acid. Explain what this means.
What is the difference between an aqueous acid and an aqueous alkali in terms of the ions they contain?
What mass of methanesulfonic acid is required to prepare $150\,\text{cm}^3$ of a $0.150\,\text{mol dm}^{-3}$ solution?
During a titration, $0.00150$ moles of NaOH are exactly neutralised by $0.175\,\text{mol dm}^{-3}$ methanesulfonic acid. Calculate the volume, in $\text{cm}^3$, of aqueous methanesulfonic acid needed for this titration.
Name the gas produced when methanesulfonic acid reacts with magnesium.
The salt contains the anion $\text{CH}_3\text{SO}_3^-$. Write down the formula of the salt that is formed.
