A solution X' gives orange colour when a drop of it falls on pH paper,while another solution 'Y' gives bluish colour when a drop of it falls on pHpaper. What is the nature of both the solutions ? Determine the pH ofsolutions X' and 'Y'.

Answer»

solution X:

◆ solution of X gives orange colour when a drop of universal indicator is added to it.◆which tells us that it is acidic In nature. ◆this means the pH would be less than 7.

solution Y:

◆solution Y gives bluish green colour when a drop of universal indicator is added to it .◆ which tells us that it would be little basic in nature.◆ this means that the pH would be more than 7.
