- Write the reaction and the corresponding Kb equilibrium expression for each of the following substances acting as bases in water. a. aniline, C6H5NH2 b. dimethylamine, (CH3)2NHarrow_forwardChloroacetic acid, HC2H2ClO2, has a greater acid strength than acetic acid, because the electronegative chlorine atom pulls electrons away from the OH bond and thus weakens it. Calculate the hydronium-ion concentration and the pH of a 0.0020 M solution of chloroacetic acid, Ka is 1.3 103.arrow_forwardNicotinic acid, C6H5NO2, is found in minute amounts in all living cells, hut appreciable amounts occur in liver, yeast, milk, adrenal glands, white meat, and corn. Whole wheat (lour contains about 60. 0g per gram of flour. One gram (1.00 g) of the acid dissolves in water to give 60. mL of solution having a pH of 2.70. What is the approximate value of Ka for the acid? Nicotinic acidarrow_forward
