Sergey Bylikin, Gary Horner and, Brian Murphy Solutions for Chapter: Acids and Bases, Exercise 5: Questions

Determine the $\mathrm{pH}$ of the solution resulting when $100 {\mathrm{cm}}^3$ of $0.50 \mathrm{mol} {\mathrm{dm}}^{-3}$ $\mathrm{HCl} \left(\mathrm{aq}\right)$ is mixed with $200 {\mathrm{cm}}^3$ of $0.10 \mathrm{mol} {\mathrm{dm}}^{-3} \mathrm{NaOH} \left(\mathrm{aq}\right)$.

Which $0.10 \mathrm{mol} {\mathrm{dm}}^{-3}$ solution would have the highest conductivity?

A student has equal volumes of $1.0 \mathrm{mol} {\mathrm{dm}}^{-3}$ sodium hydroxide and ammonia solutions. Which statement about the solutions is correct?

Which list contains only strong acids?

Which methods will distinguish between equimolar solutions of a strong base and a strong acid?

I. Add magnesium to each solution and look for the formation of gas bubbles.

II. Add aqueous sodium hydroxide to each solution and measure the temperature change.

III. Use each solution in a circuit with a battery and lamp and see bright the lamp glows.

Describe two different properties that could be used to distinguish between a $1.00 \mathrm{mol} {\mathrm{dm}}^{-3}$ solution of a strong monoprotic acid and a $1.00 \mathrm{mol} {\mathrm{dm}}^{-3}$ solution of a weak monoprotic acid.

Ethanoic acid, ${\mathrm{CH}}_3\mathrm{COOH}$, is a weak acid. Define the term weak acid and state the equation for the reaction of ethanoic acid with water.

Ethanoic acid, ${\mathrm{CH}}_3\mathrm{COOH}$, is a weak acid. Vineger, which contains ethanoic acid, can be used to clean deposits of calcium carbonate from the elements of electric kettles. State the equation for the reaction of ethanoic acid with calcium carbonate.
