Calculate the pH of a 0.0198 M aqueous solution of dimethylamine ((CH),NH, Kn=5.9x104) and the equilibrium concentrations of the weak base and its conjugate acid. PH M [(CH3)2NH)equilibrium [(CH3)2NH2 Lequilibrium = C =
An analytical chemist is titrating 221.6 ml of a 0.2800 M solution of dimethylamine (CH), NH) with a 0.2700 M solution of HNO, The pK, of dimethylamine is 3.27. Calculate the pH of the base solution after the chemist has added 190.6 ml of the HINO, solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of HINO, solution added. Round your answer to 2 decimal places....
A 0.297-M aqueous solution of (CH3)2NH (dimethylamine) has a pH of 12.1. Calculate the pH of a buffer solution that is 0.297 M in (CH3)2NH and 0.236 M in (CH3)2NH2+. pH =
Calculate the pH of 1.00 L of a 0.244 M hydrocyanic acid solution before and after the addition of 0.455 mol of sodiumcyanide. pH before addition = pH after addition =
What A chemistry graduate student is given 250. mL of a 0.40 M dimethylamine (CH), NH solution. Dimethylamine is a weak base with K -5.4 x 10 mass of (CH), NH,CI should the student dissolve in the (CH), NH solution to turn it into a buffer with pH 10.327 You may assume that the volume of the solution doesn't change when the (CH), NH,Cl is dissolved in it. Be sure your answer has a unit symbol, and round it to...
a) What is the pH of a 0.108 M monoprotic acid whose Ka is 6.097 ×10−3? b) Calculate the pH of a 0.61 M methylamine solution.

What is the pH change when 19.5 mL of 0.108 M NaOH Is added to 71.0 mL of a buffer solution consisting of 0.127 M NH3 and 0.161 M NH4? ( for ammonium ion is 5.6*10^-10.) pH change =
A 1 liter solution contains 0.244 M hydrofluoric acid and 0.325 M sodium fluoride. Addition of 0.061 moles of calcium hydroxide will: (Assume that the volume does not change upon the addition of calcium hydroxide.) Raise the pH slightly Lower the pH slightly Raise the pH by several units Lower the pH by several units Not change the pH Exceed the buffer capacity
A chemist titrates 170.0 mL of a 0.4930 M dimethylamine (CH3)NH) solution with 0.2420 M HNO, solution at 25 °C. Calculate the pH at equivelence. The p K, of dimethylamine is 3.27 Round your answer to 2 decimal places Note for advanced stu dents: you may assume the total volume of the solution equals the initial volume plus the volume of HNO3 solution added dt Save For LaterSubmit Assignment inn ights Reserved.
