Chapter 19: Q19.151 CP (page 878)

Buffers that are based on 3-morpholinopropanesulfonic acid (MOPS) are often used in RNA analysis. The useful pHrange of a MOPS buffer is $6.5$ to role="math" localid="1663323468024" $7.9$ . Estimate the role="math" localid="1663323276603" $K_{a}$ of MOPS.

Short Answer

Expert verified

The value of MOPS is $6 脳 10^{- 8}$ .

Step by step solution

Definition of Concept.

Capacity: The amount of heat energy required to raise the temperature of a body by a certain amount is known as heat capacity. The amount of heat in joules required to raise the temperature 1 Kelvin is known as heat capacity (symbol: C) in SI units.

Calculate the Ka of MOPS.

Considering the given information:

The pH range of 3-morpholinepropanesulfonic acid (MOPS) is $6.5$ to $7.9$ .

From the given pH range, calculate the average role="math" localid="1663323531566" ${pK}_{a}$ .

Average role="math" localid="1663323618817" ${pK}_{a}$ (center of range)

$= (7 . 9 + 6 . 5) / 2 = 7.2$

Calculate the role="math" localid="1663323643490" $K_{a}$ value from ${pK}_{a}$ value,

Average ${pK}_{a} =7.2$

$\begin{matrix} K_{a} = 10^{- 7.2} \\ = 6.3095734 脳 10^{- 8} \\ = 6 脳 10^{- 8} . \end{matrix}$

Therefore, the $K_{a}$ value of MOPS is $6 脳 10^{- 8}$ .
