What can you say about an unknown compound when dissolved in distilled water and with ph paper, gave an estimated ph of about 13
inn [45]

The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.

<h3>What is pH?</h3>

The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.

The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.

Therefore, the compound with a pH of 13.3 is basic.
