Question

What is the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid? A. KSO3 B. K2(SO413 C. K2S04 D. K(SO4)2 E. KSO4

Answer 1

Option C (K2SO4) is correct.

Step-by-step explanation:

Step 1: Data given

potassium hydroxide = KOH

sulfuric acid = H2SO4

Step 2: The equation

2KOH + H2SO4 → 2K+ + 2OH- + 2H+ + SO4^2-

2K+ + OH- + 2H+ + SO4^2-→ K2SO4 + 2H2O

2KOH + H2SO4 → K2SO4 + 2H2O

Now the reaction is balanced on both sides.

K2SO4 will form the salt.

Since K2SO4 is a result of the reaction H2SO4, what is a strong acid, and KOH, what is a strong base), KSO4 is a neutral salt.

Option C (K2SO4) is correct.

Answer 2

Answer : The correct option is, (C)
`K_2SO_4`

Explanation :

Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When potassium hydroxide react with sulfuric acid then it react to give potassium sulfate (salt)and water as a product.

The balanced chemical reaction will be:

`2KOH+H_2SO_4\rightarrow K_2SO_4+2H_2O`

The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.

In the balanced chemical reaction,

`KOH` and
`H_2SO_4` are reactants.

`K_2SO_4` and
`H_2O` are products.

Hence, the chemical formula of the salt produced by the neutralization of potassium hydroxide with sulfuric acid is,
`K_2SO_4`
