Writing Chemical Equations

Question 1

What is the difference between (aq) and (l)

Answer 1

(aq) means dissolved in water while (l) means liquid

Question 2

How to write ionic equation

Answer 2

Remove spectator ions, the ions that remain unchanged throughout the entire equation. (no state change)

(e.g HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
H+(aq) + OH–(aq) → H2O(l) )
