Chloroacetic acid has a relatively large equilibrium constant, so at low acid concentrations it is necessary to use the quadratic equation in order to calculate the concentrations of the aqueous species. Ka for ClCH2COOH is 1.4 ´ 10-3. For the problems that follow, consider one liter of a solution that originally had 0.0200 mol of chloroacetic acid.
What is the equilibrium concentration of [ClCH2COOH]?

Write the equation for the equilibrium that exists when nitrous acid and sodium acetate are placed in solution together (do not include spectator ions). Using published values for the Ka of nitrous acid and of acetic acid,
Ka for a weak acid HA = 3.46x10^-8, calculate K for the reaction of HA with OH- HA + OH- = A- + H2O This is an equilibrium question, but I do not understand how to find the equilibrium constant K, from the equilibrium constant of
the problem is find the pH of a solution prepared by dissolving all of the following in sufficient water to yield 1.00 L of solution :0.180 mole of chloroacetic acid (CICH2CO2H),0.020 mole ofCICH2CO2Na,0.080 mole HNO3, and 0.080
Acetic acid (CH_3COOH) is a weak acid. a) Write the symbolic equation showing the ionisation of acetic acid. b)Given that an acetic acid solution of pH 4.8 has a hydrogen ion concentration of 1.58 * 10^-5 mol L^-1, what is the
The pH of a weak monoprotic acid, HA, is 4.55. It took 39.22 ml of 0.2334 M NaOH to titrate 25.00 ml of the acid. a. Write an equation for the above reaction. b. Calculate the molarity of the weak acid c. Write the equilibrium
