Can you solve the last four questions?

Reaction # 3: Dispense 20.0 ml of 0.10M NHs into a 25 ml clean graduated cylinder, measure the conductivity recording the value to significant figures in blank below. Mark the electrolyte classification of NH, according to the measured conductivity. Pour the NH solution into a clean 50-ml beaker. Dispense 20.0 ml of 0.10MHCHO, into a clean 25 ml graduated cylinder, measure the conductivity recording the value to 3 significant figures in blank below. Mark the electrolyte classification of HCHOI according to the measured conductivity. NH, : Conductivity. - Strong weaker Nonelectrolyte HCHO: Conductivity. 145 Rio'- Strong Weak or nonelectrolyte Slowly add the HCH,0; solution in the graduated cylinder to the NH, solution in the 50 ml beaker with stirring . After thorough mixing, measure the conductivity of the reaction mixture, recording the value in the blank below. Thoroughly rinse/clean the cylinder and beaker with deionized water after measuring the mixture conductivity. The cylinder and beaker will be used in subsequent reactions. The beakers must be clean, ie. no ionic reaction mixture residue, but do not have to be dry. Solution conductivity 3.10 X 10 I The conductivity of the product solution was greater / less / the same as the reactants, Mark one! Explain the result in terms of ion concentrations of the reactant solutions and the product mixture. what type of products - strong, weak or nonelectrolytes - were formed? Write and balance the formula (molecular) equation for this reaction. Write the total ionic equation. Write the net ionic equation.

Explanation / Answer

NH3 (aq) + HC2H3O2 (aq) ---------> NH4+ (aq) + C2H3O2- (aq)

It is based on Bronsted acid-base theory. which donates a proton is an acid and which accepts is a base. NH3 is a base and acetic acid is an acid.

The above given reaction is completely balanced, ionic and net ionic equation.

Thanks.
