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.
