Question

Here are some results of solutions tested with universal indicator paper:

Sulphuric acid : Red

Metal polish : Dark blue

Washing-up liquid : Yellow

Milk of magnesia : Light blue

Oven cleaner : Purple

Car battery acid : Pink

Arrange the solutions in order of their increasing pH values (starting with the one with the lowest pH).

Open in App

Solution

The solutions have been arranged below in the increasing order of their pH values.

Sulphuric acid (~ pH 1) < Car battery acid (~ pH 2) < Washing-up liquid (~ pH 5) < Milk of magnesia (~ pH 9) < Metal polish (~ pH 12) < Oven cleaner (~ pH 14)
