Acids and Bases

Reaction Between Acid and Metals

Produces Hydrogen Gas + Salt

Hydrogen Gas is an odourless and colourless gas that extinguishes a lighted splint with a pop-sound

There will be an explosive reaction if the metal is an Alkali Metal

The lower the element is in group I, the more vigorous the reaction

This is because acids can only react in aqueous form, when they are dissolved in water.

Unreactive Metals

Silver

Gold

Copper

Electrical Conductivity

Acids can only conduct electricity while in aqueous form

PH Level

Bases have Ph >7

Acids have Ph < 7

Reaction between Acids and Bases (or metal oxides)

Produces Water + Salt

Also Known as Neutralisation

Metal Oxides or hydroxides that dissolve in water are called Alkalis

Dissociation

Acids dissociate in water to give H+ ions

Strength of acid dependent on amount of dissociation in water, Strong acid >99% dissociation, Hydrochloric Acid (HCl), Sulfuric Acid (H2SO4), Nitric Acid (HNO3), Phosphoric Acid, Weak Acid <3% dissociation, Ehanoic Acid (CH3COOH), Hydrofluoric Acid, Citric Acid, Amount of dissociation depends on Atomic Structure of Acid

Bases dissociate in water to give OH Hydroxide ions

Strong Bases, Sodium Hydroxide

Weak Bases, Aqueous Ammonia

Reaction between Acids and Carbonates

Produces Salt + Water + Carbon Dioxide

Carbon Dioxide is a colourless, odourless gas that gives off a white precipitate when bubbled through lime water

Definition

A base is a metal oxide or a metal hydroxide

An acid is a substance that produces H+ in water
