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.
