Double displacement reaction
3CaCl2 + 2Na3PO4 → Ca3(PO4)2 + 6NaCl
Calcium chloride aqueous colour is clourless (just like water calcim chloride is highly soluble in water)
Trisodium phosphate aqueous colour is clourless (just like water calcium chloride is highly soluble in water)
TriCalcium phosphate aqueous colour is clourless (just like water calcium chloride is highly soluble in water)
Complex formation reaction
FeCl3(aq) + 6KSCN(aq) → K3[Fe(SCN)6] + 3KCl(aq)
Appearance of FeCl3(aq) is brown in colour
Appearance of KSCN(aq) is colourless (just like water)
Appearance of K3[Fe(SCN)6] is blood red colour
Acid-base neutralization reaction
2 HCl (aq) + Na2CO3 (aq) → 2 NaCl(aq) + CO2 (g) + H2O (l)
The appearance of both aqueous solution of sodium carconate Na2CO3(aq) and hydrochloric acid HCl(aq) are colourless
