Question

na3po4 + koh → naoh + k3po4
decomposition
combustion
synthesis
double replacement
single replacement

Explanation:

In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. In the reaction \(Na_3PO_4+KOH
ightarrow NaOH + K_3PO_4\), the \(Na^+\) from \(Na_3PO_4\) combines with \(OH^-\) from \(KOH\) to form \(NaOH\), and the \(K^+\) from \(KOH\) combines with \(PO_4^{3 -}\) from \(Na_3PO_4\) to form \(K_3PO_4\). This is characteristic of a double - replacement reaction.

Answer:

double replacement
