Give reasons for the following:
Both `(CO_2 & SO_2)` turn lime water milky. Moist potassium permanganate paper, helps in distinguishing the two gases.

Name the gas other than CO_(2) which also turns lime water milky.

Sodium sulphite (Na_(2)SO_(3)) is added to meat as a preservative. The presence of Na_(2)SO_(4) can be detected by adding dil. H_(2)SO_(4) when the pungent smelling gas evolved turns the lime water milky. The gas evolved was detected as sulphur dioxide. The SO_(2) " to "SO_(4)^(2-) in titration. SO_(2)+2H_(2)O+I_(2) to 4H^(+)+SO_(4)^(2-)+2I^(-) In order to check the results of titration, excess barium chloride is added to the final solution. The resulting precipitate is collected and weighed. Q. SO_(2) and CO_(2) both lime water milky. Which of the following reagent can be used to distinguish these two gases? (I) K_(2)Cr_(2)O_(7)"/"H_(2)SO_(4) (II) KMnO_(4)"/"H^(+) (III) I_(2) solution

Give suitable reason(s) for each of the following: H_2SO_4 is not used to dry ammonia.

Give reasons for the following in one or two sentences only: BeCl_(2) can be easily hydrolysed'.

CO_(2) and SO_(2) both turn line water mily how will you detect the present if turn both are present in a mixture ?

Give reasons for the following: Lime water finds application for testing both carbon dioxide & carbon monoxide gas individually.

Give reasons for the following : MgCl_(2) is soluble in water but insoluble in acetone, while methane is insoluble in water, but soluble in acetone.

Give a chemical test to distinguish following gases. CO_2 and NO_2

On passing excess of CO_(2) in lime water, its milky appearance disappears because-

Give reasons for the following : Sodium hydrogen sulphate is not an acid but it dissolves in water to give hydrogen ions, according to the equation NaHSO_(4)hArrH^(+)+Na^(+)+SO_(4)^(2-)
