Neutralisation
If you mix together exactly the right amounts of acid and alkaline, you can achieve neutralisation. This experiment is called a titration. The point at which the indicator indicates that the solution is neutral is known as the end point of the titration. This experiment is often performed using a burret, a conical flask and methyol orange indicator. |

MASH
Metal + Acid ⟹ Salt + Hydrogen |
Metals above hydrogen in the reactivity series react with acids to form a salt and hydrogen |
Simple acids contain hdrogen, when the hydrogen is dispaced by the more reactive metal, the resulting compound is called a salt and the hydrogen is on its own |

Other Formula
Metal + Acid ⟹ Salt + Hydrogen |
Metal Oxide + Acid ⟹ Salt + Water |
Metal Hydroxide + Acid ⟹ Salt + Water |
Metal Carbonate + Acid ⟹ Salt + Water + Carbon Dioxide |
Ammonia + Acid ⟹ Salt (depending apon conditions) |
