# Question: What Is The PH Of 10 3 M HCl?

## 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 2 M h2so4?

pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7. Thus pH of the solution is 1.7.

The pH is 1.60.

## 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.

## What is the pH of 10 7 M HCl?

While finding the pH of HCl , we will also consider the h+ions given by the water . Hence total concentration becomes 2*10^7. Now by using formula of pH=-logH+=we get pH =6.7.

## What is the pH of M HCl?

Hi, as professor Thomas Proft said pH= -log[H3O+], thus HCl 1M has a pH=-1, however pH has been defined between 0 and 14, according to the water constant (pK=14).

## 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.

## How do I calculate 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 the pH of 10 8 M solution of HCl?

about 6.8Video Explanation The concentration of HCl is given as 10−8 M. pH is calculated based on the protons of the acid and the water. 10−8 M is a very low concentration and hence the protons from water are also considered. This gives the value of the pH of about 6.8 which is very close to 7.

## What is the pH of 10 8 M NaOH?

The pH of the solution is 7.

## How do you find 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.
