Refer the given passage and answer the following questions.
Strength of an acid solution or a basic solution can be determined by knowing the hydrogen ion concentrations in them, using a pH scale.
(i) Neutral solution has pH 7.
(ii) Acidic solution has pH less than 7.
(iii) Basic solution has pH more than 7.
The pH of a solution is inversely proportional to the hydrogen(H+) ion concentration in it.

Teacher told three students Renuka, Bhawna, and Seema to test their saliva with pH paper before and after having their lunch. Seema observed that pH paper turned yellow and recorded pH value of 5.6 -5.8 after having lunch.
