19 Ethanoic acid is a weak acid.Hydrochloric acid is a strong acid.Which statements are correct? A1 Ethanoic acid molecules are partially dissociated into ions.2 1.0 mol/dmethanoic acid has a higher pH than 1.0 mol/dm3 hydrochloric acid.3 Ethanoic acid is always more dilute than hydrochloric...
A linear titration equation for determination of weak acids in the presence of small amounts of a strong acid is derived. The titration is performed potentiometrically. Equal volumes of the titrant are added stepwisely. More satisfactory results are obtained from the determination of an extremely ...
Which of the following solutions is a weak acid? a. 0.1 M HCl b. 0.1 M HC2H3O2 c. 0.1 M NaOH d. 0.1 M NH3 Properties of Weak Acids: Weak acids are defined by a low extent of ionization when dissolved in water. The lower ion concentrations ...
