Write the equations Na3PO4 NaNO3 Al2 (SO4) 2 AlBr3 H2SO4 HgF2

We write the following EMF equations for these connections:
for sodium phosphate
Na3PO4 —–> 3Na⁺1 + + PO4 3-
for sodium nitrate
NaNO3 —-> Na 1+ + NO3 1-
for aluminum sulfate
Al2 (SO4) 3 ——- 2Al 3+ ⁺ + 3SO4 2-
for aluminum bromide
AlBr3 —-> Al 3+ + 3Br⁻1-
for sulfuric acid
H2SO4 —-> 2H + + SO4 2-
This dissociation equation is the total
for НgF2
HgF2 —-> Hg 2+ + 2F⁻1-
This salt is slightly soluble in water; only the soluble part of this salt decomposes into ions.
