Acid reacting with Bases/ Alkalis (Neutralisation Reaction )

 

Acid + Base → Salt + Water

 

  • When Sodium Hydroxide ( NaOH) , a base, reacts with Hydrochloric acid (HCl) , it forms the salt, Sodium Chloride (NaCl) and Water.

 

NaOH (aq) + HCl(aq) → NaCl (aq) + H 2 O (l)

  • When Sodium Hydroxide (NaOH) reacts with Sulphuric Acid (H 2 SO 4 ), Sodium sulphate (Na 2 SO 4 ) and Water (H 2 0)  are formed.

 

2NaOH (aq) + H 2 SO 4 (aq) → Na 2 SO 4 (aq) + 2H 2 O (l)

  • In all these neutralisation reactions , the byproduct water is formed due to the combination of hydrogen ions present in the acid and hydroxide ions present in the base. The formation of water in an acid-base reaction occurs as follows:

 

                                                                             H + (aq) + OH - (aq) → H 2 O (l)
