How will you come to know whether the concentration of electrolyte has fallen down or not?

How the concentration of electrolyte influence the stability of colloids?

You are provided with two aqueous solutions X and Y of equal molar concentrations . How will you test which one contains strong electrolyte and which one contains weak electrolyte ?

How will you test whether a given rod is made of iron or not?

How will you test whether a given rod is a magnet or not?

How will you test whether a given rod is made of iron or copper?

You enter a laboratory after a class has completed the Fountain Experiment. How will you be able to tell whether the gas used in the experiment was hydrogen chloride or ammonia ?

(a) A steady current of 2 amperes was passed through two electrolytic cells X and Y connected in series containing electrolytes FeSO_(4) and ZnSO_(4) until 2.8 g of Fe deposited at the cathode of cell X. How long did the current flow ? Calculate the mass of Zn deposited at the cathode of cell Y (Molar mass : Fe= 56 g mol^(-1) Zn-65.3g mol^(-1) , 1F -96500 C mol^(-1) ) (b) In the plot of molar conductivity (wedge_(m)) vs Square root of concentration (c^(1//2)) , following curves are obtained for two electrolytes. A and B: Answer the following : (i) Predict the nature of electrolytes A and B. (ii) What happens on extrapolation of wedge_(m) to concentration approaching zero for electrolytes A and B ?

How would you know whether a redox reaction is taking place in an acidic / alkaline or neutral medium?

How can you check whether the electric potential in a given region of space has constant value ?

The following curve is obtained when molar conductivity (wedge_(m)) is plotted against the square root of concentration, c^(1//2) for two electrolytes A and B (a) How do you account for the increase in the molar conductivity of the electrolyte A on dilution. (b) As seen from the graph, the value of limiting molar conductivity (wedge_(m)^(0)) for electrolyte B cannot be obtained graphically. How can this value be obtained?1
