Which indicator is most suitable for detecting the end point of a titration of 25.0 cm3 0.10 mol/dm3 ethanoic acid with 0.10 mol/dm3 NaOH?
If [H+] = 1.0 × 10-3 mol/dm3, what is the pH?
For the 0.10 mol/dm3 CH3COOH solution in the previous question, what is the percent ionisation (approx)?
A 0.10 mol/dm3 solution of ethanoic acid (CH3COOH, Ka = 1.8 × 10-5) is prepared. What is the pH (to two decimal places, HT method)?
Which chemical equation represents the ionisation of a weak acid HA?
What is the pH of a 0.10 mol/dm3 solution of HCl?
A student measures pH = 3.00 for an acid solution. What is [H+] (in mol/dm3)?
At the equivalence point of a titration of a strong acid with a strong base the pH is:
Given a 0.10 mol/dm3 CH3COOH solution with measured pH 2.87, calculate Ka (use [H+] from pH). Which is closest?
Which reacts faster with a metal (e.g. zinc) at the same concentration: a strong acid or a weak acid?
A tenfold dilution of a strong acid (e.g. from 0.10 M to 0.010 M) will change the pH by:
