WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … Webtwo solutions - 50 mL of A and 50 mL of B respectively. a solution of 0.2M hydrochloric acid (HCl) a solution of 0.2M sodium hydroxide (NaOH) pH meter to measure pH of the solution. Experiment 1: The pH of solution A is 7.0 i.e. it’s neutral. When we add 10 mL of 0.2M HCl to it, the pH decreases to 1.5. On the other hand, when we add 10 mL of ...
