Can filter paper dipped in silver nitrate solution instead of lead acetate paper be used for testing a sulphide?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding the Question:** The question asks if filter paper dipped in silver nitrate solution can be used to test for the presence of sulfide ions, instead of using lead acetate paper. 2. **Identifying the Chemicals Involved:** - Silver nitrate (AgNO3) is the chemical in question. - Hydrogen sulfide (H2S) is the gas that is released when sulfide ions are present. ...

Silver nitrate solution is used to study

When a copper wire is dipped into silver nitrate solution, silver is precipitated because

Assertion:When a copper wire is dipped in silver nitrate solution, there is no change in the colour of the solution. Reason : Copper cannot displace silver from its salt solution.

A gas which turns lead acetate paper black.

One half-cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknown concentration . Its other half-cell consists of a zinc electrode dipping in 1.0 M solution of Zn(NO_(3))_(2) . A voltage of 1.48 V is measured for this cell . Use this information to calculate the concentration of silver nitrate solution used. (E_(Zn^(2+)|Zn)^(@) = -0.76V , E_(Ag^(+)|Ag)^(@) = + 0.80V ).

When liquid 'A' is treated with a freshly prepared ammoniacal silver nitrate solution it gives bright silver mirror. The liquid forms a white crystalline solid on treatment with sodium hydrogen sulphate. Liquid 'B' also forms a white crystalline solid with sodium hydrogen sulphate. but it does not give test with ammoniacal silver nitrate. Which of the two liquids is aldehyde? Write the chemical equations of these reactions also.

Salts A, B, C, D and E undergo reactions (i) to (v) respectively. Identify the anion present in these salts on the basis of these reactions. Tabulate your answers in the format given below: (i) When silver nitrate solution is added to a solution of A, a white precipitate, insoluble in dilute nitric acid, is formed. (ii) Addition of dilute hydrochloric acid to B produces a gas which turns lead acetate paper black. (iii) When a freshly prepared solution of ferrous sulphate is added to a solution of C and concentrated sulphuric acid is gently poured from the side of the test-tube, a brown ring is formed. (iv) When dilute sulphuric acid is added to D a gas is produced which turns acidified potassium dichromate solution from orange to green. (v) Addition of dilute hydrochloric acid to E produces an effervescence. The gas produced turns lime water milky but does not affect acidified potassium dichromate solution.
