Question

A solution X gives orange colour when a drop of universal indicator is added to it. In the other hand, another solution Y gives blueish green colour when a drop of universal indicator is added to it. What are the types of solution X and Y and what type of pH would they have?

Answer 1

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.

{ 7 being neutral }
