I need help with this problem.

Post by immarisin »

Given the following substances: complete the reaction with the aggregation status of the products; adjustment (balance). Enter the complete ion equation and the net ion.

I already have the equation balanced, but my problem is that I don't understand the "complete ionic and the net ionic"

2K3PO4(aq) + 3Sr(NO3)2(aq) = Sr3(PO4)2(s) + 6KNO3(aq)

3 Sr2+ + 2 PO4 3- => Sr3(PO4)2(s)

All other ions will be dissolved before and after.

6 K + + 2 PO4 3- + 3 St 2+ + 6 NO3 - => Sr3( PO4)2(s) + 6 K+ + 6 NO3 -
