99. Solving a chemistry problem

Product description

• Write the equation for the dissociation of a given electrolyte (p.3) in an aqueous solution. Determine if the electrolyte is strong or weak. Write an equation for the hydrolysis of a given salt in all possible steps, indicate the reaction of the medium with an aqueous salt solution.
• Write down the expressions for the hydrolysis constants for each step. Calculate the hydrolysis constant of the indicated salt according to the 1st stage of hydrolysis.
• Calculate the pH value of the solution of this electrolyte at a given molar concentration of the salt solution C0, mol/l, taking into account only the first stage of hydrolysis.
