Question 144

In an investigation, a student added powdered magnesium oxide to dilute sulfuric acid and recorded the pH.

Their experimental method was: step 1 Measure 150 cm3 of dilute sulfuric acid into a glass beaker. step 2 Add 0.2 g of magnesium oxide powder to the beaker. step 3 Determine the pH of the mixture. step 4 Repeat steps 2 and 3 until the pH no longer changes.

State one action that should be taken immediately after step 2 to ensure that the magnesium oxide reacts fully with the acid.
