Acids bases and neutralisation Flashcards
What is the formula of hydrochloric acid?
Hcl
What is the formula of sulfuric acid?
H2SO4
What is the formula of nitric acid?
HNO3
What is the formula of ethanoic acid?
= CH3COOH
What element does all acids contain?
= hydrogen
What happens when we dissolve an acid in water?
= releases a
= hydrogen ion (H+)- strong acid
= chlorine ion (Cl-)
=
WHat happens when ethanoic acid is dissolved in water?
= small percentage of the acid molecule dissociates in the water (splits into ions)
= weak acid
= partially dissociates
What are bases?
= nuetralises acids to produce a salt
= ends in oxides, hydroxides and carbonates or hydrocarbonate
= ammonia
What happens when a base and acid reacts?
= produces salt and water
= metal ion in metal oxide replaces the hydrogen ion in the acid
What happens when a carbonate and acid reacts?
= Salt + water + carbon dioxide
What are alkalis?
= bases that dissolve in water
(soluable)
=
What are all group 1 metal hydroxides?
= soluable in water
= can form alkalis
What happens to alkalis in a solution?
= release OH ions
What is the general equation for nuetralisation?
= OH- + H+ = H2O
