State the inference drawn from the following observation:
Salt S is prepared by reacting dilute Sulphuric acid with Copper oxide. Identify S.
Explanation:
H2SO4(l)Sulfuricacid+CuO(s)Copperoxide→CuSO4(s)Coppersulfate+H2O(l)Water
A, B, C and D summarize the properties of sulphuric acid depending on whether it is dilute or concentrated. Choose the property (A, B, C or D), depending on which is relevant to each of the preparations (i) to (iii): A. Dilute acid (typical acid properties) B. Non-volatile acid C. Oxidizing agent D. Dehydrating agent (i) Preparation of hydrogen chloride. (ii) Preparation of ethene from ethanol. (iii) Preparation of copper sulphate from copper oxide.
From the list of substances given, name the substance which you would use to prepare each of the following salts, named in parts (a) to (d):
The substances are Copper, Lead, Sodium, Zinc, Copper oxide, Lead carbonate solution, dilute Hydrochloric acid, dilute Nitric acid and dilute Sulphuric acid:
(b) Copper sulphate
Copper does not react with conc. sulphuric acid but reacts with the dilute acid
