What is the pH of a 0.25 M HCl solution?

The pH is 1.60.

How do you calculate pH from acid concentration?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

### What is the pH of a 0.04 M solution of HCl?

The formula for determining pH is -log[H+]. Since your solution concentration is 0.04 M, this means that the [H+] is also 0.04 M. Thus, the pH = -log[0.04] = 1.4.

What is the pH of a 0.05 M solution of HCl?

This solution can be considered equivalent to a solution 0.1 M (0.15 – 0.05) in HCl thus pH = -Log (0.1) = 1.

What is the pH of a 0.001 M solution of HCl?

0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.

#### How do you find the concentration of OH given the pH?

Key Takeaways: How to Calculate pOH If you know pH, it’s easy to calculate pOH because pH + pOH = 14. Sometimes you need to calculate pOH from the hydroxide ion concentration [OH-]. You’ll need a calculator here, using the equation pOH = -log[OH-].

Is HCl a strong acid?

When HCl molecules dissolve they dissociate into H+ ions and Cl- ions. HCl is a strong acid because it dissociates almost completely.

What is the approximate pH value of HCl?

Chemical formula: HCl. Also known as: Muriatic acid, Spirits of salt, Hydronium chloride, Chlorhydric Acid. N 100 mM 10 mM 1 mM. Hydrochloric Acid is Strongly Acidic. At concentration of 1 mM, it has a pH of 3.01. At concentration of 10 mM, it has a pH of 2.04. At concentration of 100 mM, it has a pH of 1.08.

## What is the chemical formula for HCL?

The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor.

What is the Ka value for HCL?

Ka values can be very large or very small. For example, the Ka value for hydrochloric acid (HCl) is around 10 7, while the Ka value for ascorbic acid (vitamin C) is 1.6 X 10 -12.

How do you calculate the pH of an aqueous solution?

Calculating pH. To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H 3O +].
