Q. Define Conjugate acid-base pair and buffer?
Buffers are substances that resist changes in pH. To "balance pH" means to buffer.
Weak acids and bases make good buffers. A pair of substances that differ by only one H+ ion are called a conjugate acid-base pair and make good buffers. For example, H2Se and HSe- are a conjugate acid-base pair, as they differ by only one H+ ion.
The conjugate acid, H2Se, can produce an H+, and the conjugate base, HSe-, can accept an H+:
H2Se -> H+ + HSe-HSe- + H+-> H2Se
These reactions help to buffer a solution, and thus resist changes in the pH level.
Acid-base titrations - Types of titrations While the strength of an acid is determined along with the help of a standard solution of base, it is termed as acidimetry. Similarly
Q.How can we determine Concentrations of Solutions? Ans. The concentration of a solution is the quantitative expression of the amount of solute dissolved in the solution.
