It is a good conductor of electricity in molten state.Chloride of G has a low melting point and it dissolves readily in water to give a solution which turns blue litmus paper red. It is a non-conductor of electricity.What are the possible identities of the two fibres?A Oxide of E ...
The solid dissolves partially when water is added, forming a solution which turns red litmus paper blue. When solid phosphorus pentachloride is added, the white solid dissolves.Explain the observation as fully as you can.[3](b) The benzene ring is an important functional group for many natural...
The litmus paper test is a simple test in order to determine whether a given solution is acidic or basic. After placing a drop of solution on the litmus paper, if it changes a red litmus paper to blue, the solution is basic. If it changes a blue litmus paper to red, the so...
An aqueous solution of a gas (X) turns red litmus blue. When added in excess to copper sulphate solution, deep blue colour is obtained. On addition to a ferric .chloride solution a brown precipitate soluble in dilute nitric acid is obtained. Hence, (X) is A SO2(g) B H2S(g) C NO2...
If an aqueous solution turns blue litmus red, which relationship exists between the hydronium ion and hydroxide ion concentrations? (a) (H_3O^+) greater than (OH^-) (b) (H_3O^+) less than (OH^-) (c) (H_3O^+) = (OH^-) = 10^{-7} (d) (H_3O^+) = (...
(1) A it makes a squeaky pop with a lighted splint B it relights a glowing splint C it turns damp blue litmus paper red D it turns limewater milky(d)The student used this method to obtain a sample of magnesium sulfate crystals from the solution formed in reaction 2.. heat the ...
17. A sample of X is heated with agueous sodium hydroxide and small pieces of aluminium. A gas is produced which turns red litmus paper blue.Aqueous sodium hydroxide solution is added to a second sample of X. A pale green precipitate is observed.What is X? C A ammonium nitrate B chromi...
The main property of acids is that they release hydrogen ions when placed in an aqueous solution; this property is confirmed when a solution turns a blue litmus paper red. Other acids such as sulfuric acid are highly corrosive. The reactions between acid...
