Fill in the blank. weak bases react with to form the hydroxide ion and the conjugate of the base. concentration in solution does not affect whether an acid or a base is or weak. the strength of an acid or a base is determined by the of the substance in solution. the acid dissociation constant, is a quantitative measure of acid strength. a strong acid has a much ka than a weak acid. the ka of an acid is determined from measured values. hydrochloric acid and sulfuric acid are ionized in solution and are acids. ethanoic acid, which is only about 1 percent ionized, is a acid. magnesium hydroxide and calcium hydroxide are strong

In the acid-base chemistry experiment the measurement of ph will be used to explore acid-base concepts, analyze an unknown, and determine percent k and fe in the iron salt. the ph is measured using ph paper, acid-base indicators, and a combination ph electrode. quantitative measurements are made using a combination ph electrode interfaced with a computer in a ph titration using dilute naoh. the molarity of a strong acid (hcl), equivalent weight and pka of an unknown weak acid, and percent k and fe in your iron salt are all determined in this way. samples of the iron salt are run through a cation exchange column to prepare for titration. choose either true or false for each of the following statements : a solution with a hydronium molarity of 0.00045 is acidic. ph is a way to express the hydronium concentration over a wide range.percent k and fe are determined by doing ion exchange then a ph titration.about 0.2m hcl is the titrant used for the ph titrations. a lewis base is a species that can donate a proton to an acid
