HCl pH to Mass Calculator

Formula

To calculate the mass of HCl:

$m = \frac{C \times V \times M}{10^{-pH}}$

Where:

$m$ is the mass of HCl in grams
$C$ is the concentration of HCl in molarity (M)
$V$ is the volume of the solution in liters (L)
$M$ is the molar mass of HCl (approximately 36.46 g/mol)
$pH$ is the pH of the solution

What is HCl?

Hydrochloric acid (HCl) is a strong, corrosive acid that is commonly used in laboratory and industrial applications. It is a solution of hydrogen chloride gas in water and is known for its ability to dissociate completely in water, making it a strong acid. HCl is used in various applications such as pH control, chemical synthesis, and as a cleaning agent. It is also a component of gastric acid in the human stomach, aiding in digestion.

Example Calculation 1

Let's assume the following values:

Concentration ( $C$ ) = 0.1 M
Volume ( $V$ ) = 1 L
pH = 1

Using the formula:

$m = \frac{0.1 \times 1 \times 36.46}{10^{-1}} = \frac{3.646}{0.1} = 36.46$

The mass of HCl is 36.46 grams.

Example Calculation 2

Let's assume the following values:

Concentration ( $C$ ) = 0.05 M
Volume ( $V$ ) = 2 L
pH = 2

Using the formula:

$m = \frac{0.05 \times 2 \times 36.46}{10^{-2}} = \frac{3.646}{0.01} = 364.6$

The mass of HCl is 364.6 grams.
