A pH buffer is a solution that resists changes in pH when acids or bases are added to it—typically, a solution of a weak acid and its conjugate base. What masses of dimethylamine and dimethylammonium chloride do you need to prepare 2.00 L of pH = 12.00 buffer if the total concentration of the two components is 0.500 M? Mass of dimethylamine =  I found the answer to be 42.88 Mass of dimethylammonium chloride = (the mass of dimethylamine is correct but the mass of dimethylammonium chloride is wrong)

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
