Strong and Weak acidic base Flashcards
What are strong acid and strong base
Strong acid and strong base ionize completely in in a solution of hydrochloric sulfuric and nitric acid are strong acids.
Group 1 hydrochloric are strong eg. sodium hydroxides , potassium hydroxide.
NaOH (aqueous) arrow Na- (aq) + OH- (aq)
HCL (aqueous) arrow H - ( aq) + CL - (aq)
Weak acid and weak base
Weak acid and weak base ionize only partially in solution. There are more molecules in- ionized acid or base present that there are ions. We use double bonds to show that both products present in what we called equilibrium reactions.
What organic acid are a weak acid .
Organic acid such as ethanoic acid , CH3 OOH are a weak acid.
CH2 COOH(aq) double arrow H+(aq) + CH3COO-(aq)
What is an example of a weak acid
Ammonia is an example of a weak base.
NH3 (g) + H2O(l) double arrow NH4 - (aq) + OH-(aq)
What is acidic oxides
Acidic oxides react with alkalis to from salt and water. Many of the, Also react with water to form acid.they are all oxides of non- metal.
CO2 (g) + 2NaOH (aq) arrow Na2 CO3 (aq) + H2O (l)
Basic oxides
Basic oxides react with acidic to form salts and water. Group 1 and some Group 3 react with water to form hydroxides.
CuO(s) + H2SO4 (aq) arrow CuSo4 (aq) + H2O(l)
Li2O(s) + H2O(l) arrow 2 li OH (aq)
Amphoteric oxides
Amphoteric oxides react with both acid and alkalis. Aluminum oxides react with acids to from salts and water. And react with alkalis to from aluminum ate.
AL2 O3 (s) + 6HCL (aq) arrow 2 AlCl3(aq) + 3H2O(l)
N2 O3 (s) + 2 Na OH (aq) arrow 2 Na AlOz (aq) + H20(l)
Neutral oxides
Do not react with acid and alkalis. Nitrogen (1) oxides, NaOH,NITROGEN (11) oxides, no are neutral oxides
Reaction of acids
Reaction with metals
Most acids reacts with reactive metals to from a salts and hydrogen.
Reaction with base
Acid react with oxides to form a salt and water
Acid reacts with hydroxide to form a salt and water
