Question

11 multiple choice 1 point use the given ion charges to determine the formula for ammonium phosphate. 1+ (nh4)? 3- (po4)? (nh4)(po4) (nh4)4(po4) (nh4)(po4)3 (nh4)3(po4)

Explanation:

Step1: Balance the charges

The ammonium ion ($NH_4^+$) has a charge of $1 +$ and the phosphate ion ($PO_4^{3 -}$) has a charge of $3 -$. To balance the charges, we need 3 ammonium ions for every 1 phosphate ion.

Step2: Write the formula

The chemical formula is written by indicating the number of each ion in sub - script. So the formula for ammonium phosphate is $(NH_4)_3(PO_4)$.

Answer:

$(NH_4)_3(PO_4)$
