Question

When few drops of orange juice is added to pure water, how does the pH value vary for water? If
few drops of lemon juice is also added, will there be any more change in the pH value?​

Answer 1

Answer:

When a drop of orange juice is added to the water, the acid releases H+ ions on dissociation. This lowers its pH value making it acidic in nature. If a drop of lemon juice is added to it, the concentration of citric acid will increase further resulting in lowering the pH from 7.Orange and lemon are citrus fruits which contain citric acid in their juices. When these juices are added to pure water the acid will release H+ ions on dissociation and the pH value will decrease from 7 as the acidity increases.

Answer 2

Answer:

The pH level of Water will Slightly Decrease.  

Explanation:

Water is 7 on the pH scale meaning it is neutral. A substance is neutral when both hydrogen ion( greater in acids) and hydroxide ions ( greater in bases) balance out.

An acidic substance has a pH level of 0-6

A basic substance has a pH level of 8-14

When you add an acidic solvent  (orange juice or lemon juice) to a neutral solvent, the pH of the water lowers due to the fact that, the more acidic a substance is the lower the pH.

As only a small amount of  the acidic solvent was added to a larger proportion of water the pH only consists of slight change.
