Question

Two drinks P and Q gave acidic and alkaline reactions, respectively. One has a pH value of 9 and the other has a pH value of 3. Which drink has the pH value of 9?

Answer 1

Answer:

Q

Explanation:

Q gave alkaline reaction, which means Q is basic in nature.Therefore it will have pH more than 7.

Answer 2

The drink that has the pH value of 9 is alkaline drink.

Explanation:

• pH is the measurement to show whether the solution is a base or an acid.
• Basic solutions have high pH, whereas the acidic solutions have low pH. pH value of water is only 7.
• The pH scale inversely shows the hydrogen ions concentration in a solution; lower the pH, higher the concentration; higher the pH, lower the concentration. So, the drink Y given in the above question is an alkaline drink.
