Question

Magnesium +Hydrogen Phospahate

Answer 1

Answer:

That makes Dimagnesium phosphate

Answer 2

Answer:

The reaction between Magnesium and Hydrogen Phosphate forms Magnesium Hydrogen Phosphate

Explanation:

When magnesium reacts with hydrogen phosphate it forms an ionic compound called Magnesium Hydrogen Phosphate or Dimagnesium Phosphate.

Magnesium Hydrogen Phosphate is an ionic compound with the formula HMgO4P.

Equation;

Mg + HPO4 ------> HMgO4P

Similarly we can use Magnesium Phosphate to demonstrate the reaction.

In chemistry, the sum of charges of the anion and the cation of any ionic compound is always equal to zero.

To determine the number of anion and cation required for the sum to be zero we simply use the criss-cross method. This involves taking the charge of one ion and making the absolute value of that charge to be the amount of the other ion.

Therefore, Magnesium having a charge of 2+; we will have two(2) Phosphate cations for it.

Also, Phosphate has a charge of 3-; so we have three(3) Magnesium cations.

Equation;

$Mg^{2+} + (PO4)^{3-} ----> Mg3(PO4)2$
