Question

7. Al(OH), +H,CO, → Al,CO, +H2O
8. NH,OH + H,PO4(NH),PO, +H,O
9.
Na +Cl, NaCI​

Answer 1

Answer:

This is an acid-base reaction (neutralization): H 3PO 4 is an acid, KOH is a base. ; Thick, colorless, odorless, crystalline solid. [Note: Often used in an aqueous solution.]

...

1 KOH + H3PO4 → H2O + K3PO4

3 KOH + H3PO4 → H2O + KH2PO4

4 KOH + H3PO4 → H2O + KH2PO4 + K2HPO4

5 KOH + H3PO4 → K3PO4 + HOH
