During a titration the student obtains concordant burette readings 23.45, 23.55, 23.50 cm3 for the titrant. Which value is appropriate to use for calculations?
Which explanation is correct for why an indicator must be chosen with an endpoint close to the equivalence pH in a titration?
What happens to the pH of a fixed amount of strong acid when its concentration is increased (same acid, more moles in same volume)?
A student dilutes 0.10 mol/dm3 HCl by adding equal volume of water. What is the new concentration and approximate pH?
How does increasing the concentration of a strong acid affect the pH?
Which practical observation shows the end point of a titration of a weak acid with a strong base using phenolphthalein?
A student neutralises 25.0 cm3 of 0.100 mol/dm3 HCl with 0.100 mol/dm3 NaOH. What volume of NaOH is required?
What is the [H+] (in mol/dm3) of a solution with pH 5?
Which is a correct safety observation to make when adding acid to water in preparation of dilute acid?
Which statement about pH and concentration is true for strong monoprotic acids?
Calculate the pH of a solution with hydrogen ion concentration [H+] = 1.0 ื 10-3 mol/dm3.
