Question

We know that the items which taste sour are acidic ,so why lemon juice don't harm having sour taste?

Answer 1

.Well Lemon juice is acidic it contains citric acid.

.But the concentration of citric acid in lemon juice is only about 5% to 8%

.A 5% to 8% is a very low concentration in other words we can say it is highly DILUTED

.so the presence of this low concentraion acid will not cause any harm to us,

.Also note that citric acid is a very weak acid so its's presence is not at all harmful
