What is the pH of a 1.4 M solution of HClO4?
The pH of a 1.4 M solution of HClO4 is -0.15. Perchloric acid, or HClO4 is a strong acid.
How do you find the pH of HClO4?
1 Answer
- We use the pH equation, which states that,
- pH=−log(H+)
- And so, the pH will be,
- pH=−log(0.075)
- ≈1.12.

What is the pH of 0.1 m HClO4?
pH = 1.1 In the case of 0.1 M HClO4 (pH = 1.1), which is the electrolyte most usually reported on the literature, the onset potential in the presence of bromide is significantly displaced to more negative potentials.
What is the pH of 10 8 M HClO4?
Answer: (3) All acids have a pH in the acid range, that is to say below 7. HCl being strong acid, it completely ionizes. The concentration of H+ from ionization is equal to the (OH–) from water and let us consider it is equal to x. Total (H+) = 1.05 x 10-7.
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 a 0.0045 M solution of HClO4?
What is the pH of a 0.0045 M solution of HClO4? 2.49 | Chegg.com.
What is the pH of 1.0 m HCl?
Now, this concentration of H+ ions will be useful in determining the pH of the solution. The formula to find the pH of the solution is as below. Thus, we obtained that pH of the 1M solution of HCl is 0. So, the correct answer is (A).
What will be the pH of 10 (- 8 M solution of HCl?
As the concentration of H+ from ionisation is equal to the concentration of OH from water, let us consider it X. Hence, the pH value of 1 × 10-8 (M) HCl is 6.98.
How do you find pH from M?
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 formula?
∙ The formula for calculating pH is pH=−log(H3O+) ∙pH is the negative logarithm (to base 10) of the molar hydronium ion concentration. ∙ pH+pOH = 14 always.
What is the pH of a 0.20 m HCl solution?
Answer: HCl is a strong acid, it dissociates 100% (I.e. completely): (HCl)F = 0.020 M = (H3O+) So, pH = – log (H3O+) = -log (HCl)F = -log(. 020)=1.70 Voila!
What is the pH of a solution of 1.0 10 − 9 M HCl?
6.99 Hence, the pH of 1 × 10-9 M HCl solution is 6.99.

How do you calculate pH from M?
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 0.20 M HCl solution?
Answer: HCl is a strong acid, it dissociates 100% (I.e. completely): (HCl)F = 0.020 M = (H3O+) So, pH = – log (H3O+) = -log (HCl)F = -log(. 020)=1.70 Voila!

How do you calculate pH example?
For example, the pH of a solution with (H+)=2.3×10−5M can be found as shown below. When the pH of a solution is known, the concentration of the hydrogen ion can be calculated. The inverse of the logarithm (or antilog) is the 10x key on a calculator. For example, suppose that you have a solution with a pH of 9.14.
