Question

2. P is an aqueous Solution of orcid and Q is an aqueous Solution of base. When these two are diluted separately, then as PH of P Increases while that of a decreases til heutralisation neutralisation and a decrease h) PH of P decreases while that of Q Increases Ha es pt af both D and a decrease & PH of both and Q Increase ​

Answer 1

Dilution simply consists in adding water in an aqueous solution. It makes increase the proportion of solvent compared to that of the solute. In diluting an acidic solution the solution becomes less acidic,its pH increases and approaches 7 and dilution of of basic solution becomes less basic,its pH decreases and approaches 7. The solution becomes neutral in nature.

make me brainly please

Answer 2

Answer:

PH of P Increases while that of Q decreases til neutralisation is achieved.

Explanation:

Aqueous solution P is acidic in nature. When it is diluted, its acidity decreases due to increase in the amount of neutralising solvent. Due to decrease in acidity, the pH value increases. At neutral point, its pH will be equal to 7.

Aqueous solution Q is basic in nature. Upon dilution, its basicity decreases, and ph starts decreasing and approaches 7. When a completely neutral solution is obtained, the pH value of Q will be 7.
