IB Docs (2) Team MC test: Properties of acids & bases
Multiple choice test on 8.2 Properties of acids & bases
Use the following 'quiz' to test your knowledge and understanding of this sub-topic. You will need access to a periodic table (Section 6 of the IB data booklet).
If you get an answer wrong, read through the explanation carefully to learn from your mistakes.
Which metal will react with sulfuric acid to produce hydrogen gas?
Only zinc is above hydrogen in the activity series (see Section 25 of the data booklet).
Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide and water.
What is the sum of the five coefficients in the stoichiometric equation?
2HCl(aq) + 1CaCO3(s) → 1CaCl2(aq) + 1CO2(g) + 1H2O(l)
Which reaction can be classified as a reaction between an acid and an alkali?
An alkali is a soluble base. The only soluble base in the list is potassium hydroxide.
Which are correct statements about the reactions of hydrochloric acid with metal carbonates?
I. The reactions are exothermic.
II. Carbon dioxide is always evolved.
III. Hydrochloric acid only reacts readily with solid metal carbonates.
The ionic equation for the reaction taking place is CO32− + 2H+(aq) → CO2(g) + H2O(l) and it does not matter whether the carbonate ion is a solid or in aqueous solution.
Which reagents react together to produce copper sulfate?
Copper oxide is a basic oxide and neutralizes sulfuric acid CuO + H2SO4 → CuSO4 + H2O. None of the other reagents will react to produce a sulfate ion.
Which reagents will react together to produce ammonia?
The ionic equation is NH4+ + OH− → NH3 + H2O. The only base present is sodium hydroxide.
Which reagents do not produce water as one of the products when they react together?
When reactive metals react with an acid they produce a salt and hydrogen, but no water.
Which is not a neutralization reaction?
The ionic reaction between hydrochloric acid and silver nitrate is Ag+(aq) + Cl−(aq) → AgCl(s) which is an example of a precipitation reaction.
Bromophenol blue is an indicator which is yellow in acid solution and blue in alkali solution.
Which will turn the indicator blue?
Chlorine and carbon dioxide both give acidic solutions in water. Ammonia and copper oxide are both bases but copper oxide is insoluble in water so will not make an alkaline solution.
Which sodium compound will not neutralise an acid?
Oxides, carbonates and hydrogencarbonates are all bases and can neutralize acids. Sodium sulfate is the salt formed when sulfuric acid is completely neutralized by sodium hydroxide and it cannot react further with an acid.
