Hi there!!

pH is a measure of hydrogen ion concentration; a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. Aqueous solutions at 25°C with a pH less than seven are acidic, while those with a pH greater than seven are basic or alkaline.

The stomach juice of A is more acidic because according to pH scale, the ones which goes lesser than 7 is acidic and how far we go back from 7 acidity of the substance increases...

Hope it helps you...
Thank you...
