What is the pH of 0.1 m of 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 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 a 0.0250 m HClO4 solution?
Substituting 0.025 into the equation for pH we find that the 0.025 M HCl solution has a pH of -log(0.025) = 1.60.
How do you find the pH from molarity 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.

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 0.20 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 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.

Is HClO4 an acid or base?
HClO4 is a strong acid. Because it readily dissociates in an aqueous solution, which means no dissociated parts of it remain in the solution, all parts completely break off and are ionized in an aqueous solution.

What is the pH of a 5.0 M solution of HCl?
5M HCl is about 5.5m, and activity coefficient is dramaticly increasing with concentration (see table I of the pH paradox reference) so the true pH deviates somewhat further from -0.69, but pH = -1.1 is a reasonable estimate.
What is the pH of a 1.0 m HCl solution?
0 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 is the pH of a 0.0001 m solution of HCl?
The pH and pOH of 0.0001 M HCl solution are 4 and 10 respectively.
What is the pH of a 1.0 M HCl solution?
0 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).
