Question: What Is The PH Value Of 10 M HCl?

What is the pH of 10 9 M HCl?

Since its concentration is very low, you need to account for H+ ions of water as well.

Hence total amount of H+ ions present will be 10^-9 + 10^-7 =1.01*10^-7.

Hence pH would be -log(1.01*10^-7) = 6.99567..

What is the pH of 10 8 M NaOH?

The pH of the solution is 7.

What is the pH of blood?

Your blood has a normal pH range of 7.35 to 7.45. This means that blood is naturally slightly alkaline or basic. In comparison, your stomach acid has a pH of around 1.5 to 3.5. This makes it acidic.

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 10 2 M HCl?

thus pH defined by -log H+ is not only of therotical significance but in fact cannot be read directly. It has therefore came to be accepted that pH = -log aH+ i.e., pH of 10^2 M HCl cannot be calculated until fH+ is not known and is practically lie near to zero.

What is the pH of 10 m HCl?

pH of Solution with Very Dilute Acid In this problem, a 10 – 10 M solution of HCl contributes 10 – 10 M [H +]. The ionization of water contributes 10 – 7 M [H +]. The effective [H +] of this solution is 10 – 7 M and the pH=7.

How is pH value calculated?

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 HCl and NaOH?

HCl is a strong acid so its pH is -log1 = 0. NaOH is a strong base so hydrogen ion is 1E-14 ÷ 1 = 1E-14, hence its pH is 14.

Is 1m HCl dangerous?

How dangerous is a 1 molar solution of HCl? 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 the pH of 1.0 10 7m HCl?

1. The pH of a 1.0 X 10^-7 M HCl aqueous solution is 6.79, and not 7.00 as you might expect with a simple pH = -log[H3O+] calculation.

How do you find the pH of 1m HCl?

The pH of an aqueous solution is equal to the negative logarithm (base 10) of the Molar concentration of hydronium ions. The log of 1 is 0, since = 1. And -0 = 0. So the pH of a 1 M solution of HCl should be right around zero.

How do you calculate the pH of HCl?

Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100 M.) The pH is thus –log(0.100) = 1.000.
