Quick Answer: How Do You Calculate The PH Of HCl?

How do you find the 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 [H3O+]..

What is pH of 1m NaOH?

NaOH is a strong base so hydrogen ion is 1E-14 ÷ 1 = 1E-14, hence its pH is 14.

What is the pH of 1m of HCl?

The pH of 1 M hydrochloric acid is zero. The reason is that pH is defined as negative 1 times the log base 10 of [H+], or the proton concentration in moles per liter.

What is the pH of 0.05 M HCl?

1.3Because it’s a strong acid and it fully dissolves , the concentration of [HCl] equals to the [H+] (H3O+) concentration therefore : [H+]= 0.05M. pH=-log[H+] pH=-log(0.05)=1.3.

What is the pH of HCl in stomach?

Parietal cells contain an extensive secretory network (called canaliculi) from which the hydrochloric acid is secreted into the lumen of the stomach. The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, a level maintained by the proton pump H+/K+ ATPase.

What is the pH of HCl in water?

According to this calculation, the initial concentration of HCl is 1 x 10-3 M. If we assume that this acid dissociates completely, the [H3O+] ion concentration at equilibrium is 1 x 10-3 M. The solution prepared by adding one drop of 2 M HCl to 100 mL of water would therefore have a pH of 3.

What is the pH of a 0.02 M solution of HCl?

1.7Since HCl is a strong acid it completely dissociates. Therefore all the H+ protonates water molecules to give H3O+. Its concentration here is high enough to ignore H3O+ contribution from water so the pH is just -log(0.02) = 1.7.

What is the pH of a 0.25 M HCl solution?

The pH is 1.60.

What is the pH of a 0.01 M solution of HCl?

2.00The pH of a 0.01 M HCl solution is very, very close to 2.00 because the activity is close to the concentration in dilute solutions.

What is the pH of 6 M HCl?

The pH would be 6 because HCl is a strong acid. It dissociates completely in water. If you put in 10-6 moles then 10-6 moles will dissolve…you get 10-6 moles of Cl- ions and 10-6 moles of H+ ions. The pH is the negative log of the concentration of H+ ions in the water.

What is the pH of a .10 M solution of HCl?

The calculated pH of 10M of HCl is, -1.

What is the pH of 0.05 m NaOH?

Here, the molarity of the solution is 0.05M. That means,every 1 litre solution has 0.05 M NaOH in it. Further, the dissociation is practically 100%. => pH = 14 – pOH = 14 – 1.30102999566 = 12.699 (approx.)

What is the pH of a 0.035 M HCl solution?

Answer and Explanation: The pH of the solution is 1.46.

Is 1m HCl dangerous?

If you have to ask this question, you are clearly not a chemist and therefore a 1 molar solution of HCl is dangerous to you. Do not drink it. Do not wash you face in it.

What is pH of 0.01 m Naoh?

For example, the pOH at a 0.01 M solution of sodium hydroxide is 2, the pH of the same solution must be 14-2 = 12.

What is the pH of a 0.00100 M solution of HCl?

[H3O+]=[HCl]=0.001 M. This means that the pH of the solution will be.pH=−log(0.001). pH=3.

What is the pH of a 1×10 4 M HCl solution?

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.
