Answer: The salt obtained is potassium phosphate.
Step-by-step explanation:
When an acid reacts with a base and leads to the formation of a salt and water, it is known as neutralization reaction. The general chemical equation used to represent this reaction is:

The salt formed from the reaction of phosphoric acid and potassium hydroxide is given by the equation:

By Stoichiometry of the reaction:
2 moles of phosphoric acid reacts with 6 moles of potassium hydroxide to produce 2 moles of potassium phosphate and 6 moles of water.
Hence, the salt formed is potassium phosphate.
