Concentration of Acid - (Measured in Mole per Cubic Meter) - The Concentration of Acid is the number of moles of acid dissolved in 1 liter of solution.

STEP 1: Convert Input(s) to Base Unit

Negative Log of Acid Ionization Constant: 2.5 --> No Conversion Required
Concentration of Salt: 50 Mole per Liter --> 50000 Mole per Cubic Meter (Check conversion here)
Concentration of Acid: 15 Mole per Liter --> 15000 Mole per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

pH = pK_a+log10(C_salt/C_acid) --> 2.5+log10(50000/15000)

Evaluating ... ...

pH = 3.02287874528034

STEP 3: Convert Result to Output's Unit

3.02287874528034 --> No Conversion Required

FINAL ANSWER

3.02287874528034 ≈ 3.022879 <-- Negative Log of Hydronium Concentration

What is pH scale?

pH is a scale used to specify the acidity or basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of H ions) are measured to have lower pH values than basic or alkaline solutions. pH ranges from 1 to 14.

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.
