Question

A solution of X gives orange colour when a drop of universal indicator is added to it.On the other hand,another solution Y gives bluish green colour when a drop of universal indicator is added to it .what are the type of solutions X and Y and what would be their pH

Answer 1

aloha!

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 }

hope it helps :)

Answer 2

So here you go.

a)X is weakly acidic as it gives orange colour.

Y is Weakly basic as it gives bluish green.

b)pH of X=3-6.

pH of Y=7-9.

Thanks.
