Question:

Write a balanced chemical equation for aluminium carbonate and phosphoric acid?

Hi, guys.Please the equation for aluminium carbonate and phosphoric acid:Al2(CO3)3 + H3PO4 -gt; AlPO4 + H2O + CO2I just can't seem to balance it.

Answer:

Since you have 2 Al on the left, you need 2 Al on the rightThat gives you 2 PO4 on the left, so you need 2 H3PO4 on the leftThen, you have 3 CO3 on the left, so you need 3 CO2 on the rightThat leaves you with 3 extra O and 6 extra H, which makes 3 H2OThe balanced equation is: Al2(CO3)3 + 2 H3PO4 - 2 AlPO4 + 3 H2O + 3 CO2
