Question

two drops of phenolphthalein indicator is added to the salt solution formed on reaction and acid with base then the solution turn into pink write the strength of acid and base​

Answer 1

Answer:

Strength = Molarity * Molecular mass

Answer 2

The strength of the base is greater than the strength of the acid used since the salt formed is basic in nature.

• Phenolphthalein indicator is used to check whether a solution is acidic or basic in nature.
• Phenolphthalein indicator changes its color in acidic and basic mediums. It is colourless in acidic medium while it turns pink in basic medium.
• Since the colour of the solution is pink, the salt is basic in nature.
• Hence the salt must be formed using a strong base and a weak acid.
