Calculate the standard cell potentials of galvanic cells in which the following reactions take place: Write the Nernst equation and emf of the following cells at K: In the button cells widely used in watches and other devices the following reaction takesplace: Define conductivity and molar conductivity for the solution of an electrolyte.

Discuss their variation with concentration. The conductivity of 0. Calculate its molar conductivity. The resistance of a conductivity cell containing 0. What is the cell constant if conductivity of 0. The conductivity of sodium chloride at K has been determined at different concentrations and the results are given below: Calculate its molar conductivity and if for acetic acid is How much charge is required for the following reductions: How much electricity in terms of Faraday is required to produce i How much electricity is required in coulomb for the oxidation of i 1 mol of H2O to O2.

A solution of Ni NO3 2 is electrolysed between platinum electrodes using a current of 5 amperes for 20 minutes. What mass of Ni is deposited at the cathode? A steady current of 1. How long did the current flow? What mass of copper and zinc were deposited?

Using the standard electrode potentials given in Table 3. Predict the products of electrolysis in each of the following: Can you store copper sulphate solutions in a zinc pot?


Consult the table of standard electrode potentials and suggest three substances that an oxidise ferrous ions under suitable conditions. Calculate the potential of hydrogen electrode in contact with a solution whose pH is Calculate the emf of the cell in which the following reaction takes place: The cell in which the following reactions occurs: Why does the conductivity of a solution decrease with dilution?

Chemistry: Wikis Thus, the formation of hydrochloric acid from hydrogen and chlorine is correctly represented by the equation H2+C12=2HC1; that is to say, a molecule of hydrogen and a molecule of chlorine give rise to two molecules of hydrochloric acid; whilst the following equation merely represents the relative weights of the elements.

What is the equation for formation of benzamide from benzoic acid and ammonia? Conversion of terephthalic acid to benzoic acid is shown in Figure naphthalene dicarboxylic acid is converted to naphthoic acid. Under hydrothermal and supercritical water conditions, 1- and 2-naphthoic acids are also more reactive than benzoic acid.

The amount of a substance which furnishes or reacts with 1 mol of H+ (acid-base), 1 mol of electrons (redox), or 1 mol of a univalent cation (precipitation and complex formation). Equivalent weight. The mechanism starts with the absorption of benzoic acid into the cell, Sodium benzoate is produced by the neutralization of benzoic acid with sodium hydroxide.

Sodium benzoate can also be prepared by adding benzoic acid to a hot concentrated solution of sodium carbonate until effervescence ceases, the solution is then evaporated, cooled and.
