What is the pH of 10 7 M HCl?
6.95So we see concentrration of water as 10^-7(H+ concenrration) .
And form a quadratic equation .
H+ concentration = concentration of HCL + CONCENTRARIOB OF WATER.
The PH of a dilute solution of HCl is 6.95..
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.
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 1 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 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 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.
What is the pH of 2n HCl?

What is the pH of 10 3 M HCl?
It is a salt of a strong acid and a strong base. So its pH=7. So at a Concentration of 10^-3 or 0.001 M, the pH=7. For 10^-3M HCl the [H+] concentration is 0.001, so its pH= 3 .
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.
Can pH be negative?
It’s definitely possible to calculate a negative pH value. … In practice, any acid that yields a concentration of hydrogen ions with a molarity greater than 1 will be calculated to have a negative pH. For example, the pH of 12M HCl (hydrochloric acid) is calculated to be -log(12) = -1.08.
What is the pH of 10 8 N HCl?
6.95The Concentration of H+ released from water is 10-7 as the pH of water is equal to 7. Hence the pH of 10-8 N solution of HCl = 6.95.
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.
Is HCl a strong acid?
HCl is a strong acid because it dissociates almost completely. By contrast, a weak acid like acetic acid (CH3COOH) does not dissociate well in water – many H+ ions remain bound-up within the molecule.
