Question

An acid (X) reacts with a base (Y) to produce Mg3(PO4)2. What are X and Y?

Answer 1

X = H3PO4; Y = Mg(OH)2

Step-by-step explanation:

Answer 2

Answer : The X and Y are,
`H_3PO_4` and
`Mg(OH)_2`

Explanation :

Acid-base reaction : It is a neutralization reaction in which an acid react with a base to give salt and water as a product.

When phosphoric acid react with the magnesium hydroxide base to give magnesium phosphate and water as a product.

The balanced acid-base reaction will be,

`2H_3PO_4+3Mg(OH)_2\rightarrow Mg_3(PO_4)_3+6H_2O`

X =
`H_3PO_4` = phosphoric acid = Acid

Y =
`Mg(OH)_2` = magnesium hydroxide = Base

Hence, the X and Y are,
`H_3PO_4` and
`Mg(OH)_2`
