pK_b = pOH-log10(C_salt/C_base)
This formula uses 1 Functions, 4 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Negative Log of Base Ionization Constant - Negative Log of Base Ionization Constant gives us the base ionization constant on a pH scale.
Negative Log of Hydroxyl Concentration - The Negative Log of Hydroxyl Concentration gives us the value of hydroxyl concentration on the pH scale.
Concentration of Salt - (Measured in Mole per Cubic Meter) - The Concentration of Salt is the number of moles of solute dissolved in 1 liter of solution.
Concentration of Base - (Measured in Mole per Cubic Meter) - The Concentration of Base is the number of moles of base dissolved in 1 liter of solution.

STEP 1: Convert Input(s) to Base Unit

Negative Log of Hydroxyl Concentration: 8 --> No Conversion Required
Concentration of Salt: 50 Mole per Liter --> 50000 Mole per Cubic Meter (Check conversion here)
Concentration of Base: 25 Mole per Liter --> 25000 Mole per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

pK_b = pOH-log10(C_salt/C_base) --> 8-log10(50000/25000)

Evaluating ... ...

What is pKb scale?

The pKb is the negative base-10 logarithm of the base dissociation constant (Kb) of a solution. It is used to determine the strength of a base or alkaline solution. The lower the pKb value, the stronger the base. As with the acid dissociation constant, pKa, the base dissociation constant calculation is an approximation that is only accurate in dilute solutions.

What is a buffer solution?

A buffer solution (more precisely, pH buffer or hydrogen ion buffer) is an aqueous solution consisting of a mixture of a weak acid and its conjugate base, or vice versa. Its pH changes very little when a small amount of strong acid or base is added to it.
