Net equation 14/2

Happy Valentine's day




Net Equation has shown that in double replacement reactions, some ions participate in the reaction while other ions do not participate.

Ex.
KCl(aq) + AgNO3(aq)  >  KNO3(aq) + AgCl(s)

Step 1: Divide the NON - INVOLVED  ions (ions that's not participate to form solid) into element

K(aq) + Cl(aq) + Ag(aq) + NO3(aq)  >  K(aq) + NO3(aq) + AgCl(s)

Step 2: Reduce one on each side, just like doing math

Ag(aq) + Cl(aq) > AgCl(s)   << done  NET EQUATION
