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 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.
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 HClO?
HClO has pKa =7.53.
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.
How do you find pH from M?

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.

How strong is HClO4?
It is corrosive to metal and tissue. It has a pKa lower than -9. It is one of the strongest mineral acids and stronger acids than H2SO4 and HNO3. It has a boiling point of 203 °C and a melting point of −17 °C.
What is pH of a solution?
The pH of a solution is a measure of hydrogen (H+) ion concentration, which is, in turn, a measure of acidity. Pure water dissociates slightly into equal concentrations of hydrogen and hydroxyl (OH−) ions: (5.16)
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.

What is the formula for calculating pH?
pH is defined by the following equation, pH = −log (H+) , where (H+) denotes the molar hydrogen ion concentration. Notice that we are required to take the common (base 10) logarithm of the hydrogen ion concentration in order to calculate pH.
