An acid (X) reacts with a base (Y) to produce Mg3(PO4)2. What are X and Y? X = H3PO3; Y = Mg(OH)2 X = H3PO4; Y = Mg(OH)2 X = H3PO4; Y = Ca(OH)2 X = H3PO3; Y = Ca(OH)2

Respuesta :

2) X = H3PO4; Y = Mg(OH)2 

2H3PO4 + 3Mg(OH)2 ----> Mg3(PO4)2 +6H2O

Answer: X = [tex]H_3PO_4[/tex]; Y = [tex]Mg(OH)_2[/tex]

Explanation: When an acid reacts with the base then it undergoes neutralization to form a salt and water.

An acid is a substance that ionizes in the water to give hydrogen ion and have pH less than 7.

[tex]H_3PO_4\rightarrow 3H^++PO_4^{3-}[/tex]

A base is a substance that ionizes in the water to give hydroxide ion and has pH more than 7.

[tex]Mg(OH)_2\rightarrow Mg^{2+}+2OH^-[/tex]

Salts are neutral compounds with pH equal to 7.

[tex]2H_3PO_4+3Mg(OH)_2\rightarrow Mg_3(PO_4)_2+6H_2O[/tex]
