Self-test J.2B

Postby ChristianM3F » Tue Dec 03, 2019 5:33 pm

Write the chemical equation for a neutralization reaction in which calcium phosphate is produced.
HPO4 + CaOH -> CA3(PO4)2 + H2O
Well, I found that out... I hope this is right. But could I have help balancing it? (Also correct me if the entire equation is wrong HAHA)

The HPO4 doesn't seem to fit here. It'd be best to use H3PO4. Also, Ca has a 2+ charge, so calcium hydroxide is actually Ca(OH)2. Using these compounds, the reaction will look like this: 2 H3PO4 + 3 Ca(OH)2 -> Ca3(PO4) + 6 H2O

You would need to add a subscript of 3 for the hydrogen because phosphate has a 3- charge.
