b) If you add a small amount of an alkali such as sodium hydroxide solution to the buffer solution, again the pH doesn't change much. Explain what happens to the extra hydroxide ions you have added. 4. In all these questions, Ka for ethanoic acid = 1.74 x 10-5 mol dm-3. a) Calculate the pH of a buffer solution containing

Their basic properties include the reactions with dilute acids, water and copper(II) ions. It only deals with amines If the reaction is in solution in water (using a dilute acid), the ammonia takes a hydrogen ion (a proton) from a hydroxonium ion. (Remember that You could also write this last equation as: . . . but if you do it

24 Apr 2017 A buffer is an aqueous solution designed to maintain a constant pH, even when exposed to small amounts of acids or bases. Whether acidic (pH < 7) or basic (pH > 7), a buffer solution consists of a weak acid or base mixed with the salt of its conjugate base or acid, respectively. To calculate the specific pH
Note: If you have a very weak acid and one of its salts, this can produce a buffer solution which is actually alkaline! I will comment briefly about this further down the page, but if you are doing buffer solutions at an introductory level this isn't likely to bother you. If you need to know about calculations involving buffer solutions,

When concentrated ammonia solution (ammonium hydroxide) is added to a clear, light blue, aqueous solution of copper(II) chloride, a powdery, light blue precipitate of copper(II) hydroxide forms. Further addition of ammonia causes the copper ion to go back into solution as a deep blue ammonia complex. The addition of

Chemguide – answers b) The hydroxide ions react with ammonium ions: 4. a). In buffer solution calculations we assume that all the ethanoate ions come from the sodium ethanoate, and the acid is almost un-ionised. Therefore: b) c) First you need to find the hydrogen ion concentration in a solution of pH 5.00. You should
