Colourless solution of the following four salts are placed separately in four different test tubes and a strip of copper is dipeed in each one of these. Which solution will turn blue?
Option (B) is correct.
$$AgNO_3$$ will turn the copper solution blue. Blue colour is due to formation of $$Cu^{2+}$$ ions. Silver comes above copper in the electrochemical series. $$Zn$$ and $$K$$ are placed below copper in electrochemical series. Thus copper can displace silver ions from its salt solution but K and Zn cannot displace silver ions from its salt solution.
Assign A, B, C, D from given type of reactions. A for precipitate formation reaction. B for precipitate dissolution reaction. C for precipitate exchange reaction. D for no reaction. $$2AgNO_3+Na_2C_2O_4 \longrightarrow Ag_2C_2O_4\downarrow +2NaNO_3$$
Assign A, B, C, D from given type of reactions. A for precipitate formation reaction. B for precipitate dissolution reaction. C for precipitate exchange reaction. D for no reaction. $$NaCl+AgNO_3 \longrightarrow AgCl\downarrow+NaO_3$$

Silver nitrate solution is kept in brown bottles in laboratory because:
Which of the following will not give a precipitate with $$AgNO_3$$?
Silver nitrate is usually supplied in coloured bottles because it is:
In solution of $$ AgNO_3 $$, if Cu is dipped in the solution, the solution become blue due to
