1
Sulfuric Acid LO: Outline uses and reactions involving Sulfuric Acid Starter: What is an acid?
2
Uses of Sulfuric Acid Production of fertilisers Used in the manufacture of: – HCl – nitric acid – Sulfate salts – Synthetic detergents – Dyes and pigments – Explosives – Drugs
3
Practical Reacting sulfuric acid with: ObservationsRelevant word equation Zn Fe CaO Ca(OH) 2 NaOH
4
Equipment needed per group: Zn Fe CaO Ca(OH) 2 NaOH 5 test tubes 1 test tube rack Googles
6
Word and formula equations RULE: METAL + ACID SALT + WATER Zinc + Sulphuric Acid Zinc Sulphate + Hydrogen (Zn + H 2 SO 4 → ZnSO 4 + H 2) Iron + Sulphuric Acid Iron Sulphate + Hydrogen (Fe + H 2 SO 4 → FeSO 4 + H 2)
7
Acid usedSecond part of salt's name hydrochloric acidchloride sulphuric acidsulphate nitric acidnitrate These are the rules for the second part of the name of a salt: These are reactions where the metal has neutralized the acid and created hydrogen gas. We could collect and test for this using a lighted splint and the classic squeaky ‘’pop’’
8
copper oxide + sulphuric acid →copper sulphate + water (CaO + H2SO4 -> CaSO4 + H2O) EXOTHERMIC = GIVES OUT HEAT
9
NEUTRALISATION REACTIONS: RULE: ALKALI + ACID → SALT + WATER calcium hydroxide + sulphuric acid → calcium sulphate + water (Ca(OH)2 + H2SO4 ==> 2H2O + CaSO4) sodium hydroxide + sulphuric acid → sodium sulphate + water (H 2 SO 4 + 2NaOH → Na 2 SO 4 + 2H 2 O)
