Question

Determine the formula of chromic acid.

Answer 1

The formula for chromic acid is H2CrO4. It is an acid formed when chromium(VI) oxide reacts with water. Chromic acid is a strong oxidizing agent.

Step-by-step explanation:

The formula for chromic acid is H2CrO4. It is an acid that is formed when chromium(VI) oxide reacts with water. The balanced equation for this reaction is:

H2CrO4 + H2O → H3O+ + CrO4^2-

Chromic acid is a strong oxidizing agent and is commonly used in various chemical reactions.

Answer 2

Answer: The formula of chromic acid is
`H_2CrO_4`

Step-by-step explanation:

We are given an ionic compound named as chromic acid. This acid is formed by the combination of hydrogen ion and chromate ion.

An acid is defined as the substance which releases hydrogen ion when dissolved in water.

Hydrogen is the 1st element of periodic table having electronic configuration of
`1s^1`.

This element will loose 1 electron to form
`H^(+)` ion.

Chromate ion is a polyatomic ion having chemical formula of
`CrO_4^(2-)`

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for the given compound is
`H_2CrO_4`

Thus, the formula of chromic acid is
`H_2CrO_4`
