Question

Complete the balanced molecular chemical equation for the reaction below. If no reaction occurs, write NR after the reaction arrow. LiCl(aq) + K3PO4(aq) → 30,2- Reset 1 2 3 4 5 6 7 8 9 0 (s) (1) (g) (aq) NR OKLICP • x H₂O

Answer 1

3 LiCl(aq) + K3PO4(aq) — Li3PO4(aq) + 3 KCl(aq) This reaction is an example of double replacement In K3PO4, the ions are present are K* and PO43- In LiCl, the ions are present are Lit and cl

In balancing the chemical equation, the number of atoms on the both sides should be same.

For writing the formulas for ionic compounds one has to use the criss cross method as shown below cation C+ aniona A cation having charge c+ and an anion having charge a-, to write the ionic compound, by combining these two ions, criss cross method of charges between cation and anion has to be used as shown below cation anion cationa- anionc (ionic compound) cation charge (c+) becomes subscript of anion and anion charge (a-) becomes subscript of cation
