GCSE Edexcel Chemistry Titrations: Potassium hydroxide reacts with

Question

Potassium hydroxide reacts with hydrochloric acid to form potassium chloride and water.

potassium hydroxide + hydrochloric acid → potassium chloride + water.

(a) A student carried out a titration to find the exact volume of dilute hydrochloric acid that reacted with 25.0 cm³ of potassium hydroxide solution.

There were five steps in the titration.
The steps shown are not in the correct order.

step J Pour the potassium hydroxide solution into a conical flask and add a few drops of indicator to this solution

step K Fill a burette with the dilute hydrochloric acid and record the initial reading from the burette

step L Use a measuring cylinder to obtain 25 cm³ of potassium hydroxide solution

step M Take a final reading from the burette and calculate the volume of the dilute hydrochloric acid reacted

step N Run the dilute hydrochloric acid from the burette into the conical flask until the indicator changes colour.
