Definition A buffer solution is one which resists changes in pH when small quantities of an acid or an alkali are added to it. Acidic buffer solutions An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts-often a sodium salt.
ANSWER: If you are using a pH 7 buffer solution to check pH using your DR/820, 850, 890, or Pocket Colorimeter and the reading is not close to what it should be, then make sure the buffer you are using is colorless (Cat.No. 12222-49 or 12222- 56) and not yellow.NSWER: The lower the temperature, the higher the impedance of pH glass. For every 10 C decrease in temperature, the glass impedance will increase about 2.5 times, resulting in slow response. For example, if the pH glass impedance is 100 MOhm at 25 C it will increase to 250 MOhm at 15 C.
