Two samples are given. Sample A = HCL(Hydrochloric acid) , Sample B(sodium hydroxide) = NaOH.
Hydrochloric acid is an acid that can turn the blue litmus into red while sodium hydroxide is a base that can turn the red litmus blue.
pH is considered as the figure that can express the alkalinity or acidity of the solution on the logarithmic scale. pH 7 can be neutral.
