when do you use the buffer solution?

Answer 1

A buffer solution is a solution of a weak acid and a weak base, which will work in such a way that it can "absorb" a large amount of acid or base before changing its pH.

Answer 2

U use buffer solution when u want to maintain the pH value of a solution. Acidic buffers keep pH below 7 & alkaline above 7

Answer 3

If you have a pH meter than to show correct pH by the meter it is required to be calibrated by buffer first with the buffer of 4,7 and after calibration you can check the pH to get accurate result

Second use is in some reactions there is requirement of have a specifec pH which are maintain by using Buffer solutions

Answer 4

Buffer solution resists the change in PH.

Answer 5

Buffer solutions (Buffers), composed of weak acids or bases and their corresponding salts are of great importance in chemistry because they have the property of resisting changes in PH both upon dilution and upon addition of strong acids and bases.for that they are playing an important role in the living systems.

Answer 6

A buffer solution is one which holds a articular pH even when contaminants are added. Many bio-chemical processes depend on controlled pH (digestion) and natural buffering occures in such circumstances.

Answer 7

A buffer solution is composed of a weak acid and a salt of its conjugate base (basically, remove a hydrogen) or a weak base and a salt of its conjugate acid (add a hydrogen). The first IS appropriate. It is a weak acid (CH3COOH) and a salt of the conjugate base (a salt of the acetate ion, in this case sodium acetate), so it satisfies the conditions. The second is NOT appropriate. While it is an acid and a salt of the conjugate base, the acid, HCl, is a strong acid, not a weak one. The third IS appropriate. It is a weak base (NH3, essentially THE classic weak base for chem classes) and a salt of its conjugate acid (NH4+; the salt is NH4Cl), so the conditions are satisfied. The fourth is NOT appropriate, because it is not a conjugate acid-base pair. Actually, both are bases. I hope this helps.

Answer 8

it keeps the system fairly constant when youre looking at pH. its made from a weak acid/base and the salt of that acid/base. addition of a strong acid will react with either the base or the salt of the weak acid to keep the pH up. addition of a strong base will react with either the acid or the salt of the weak base to keep the pH down. you use a buffer solution in your blood every day, because if your body varies too much in pH, you could die.

Answer 9

when th ph of a particular solution is neeeded to be kept constant
even with the addition of some weak acid or base a buffer solution is required it may be either a solution of strong acid and its weak salt or a weak acid and its strong salt

Answer 10

we use buffer solutions to maintain the ph value in respective chemical reactions
