Sagot :
The pH of the bleach Solution lies between the value of 11-13.
Bleach Solution: This is a water-based solution with a concentration of sodium hypochlorite and sodium hydroxide. Most commonly used for cleaning supplies in households and commercial purposes.
The pH solution of OH is 10.
To calculate the pH we need to find the concentration of [H⁺] ions
We know the relation:
[OH⁻]*[H⁺] = 10⁻¹⁴
Given [OH⁻]=10⁻⁴ substitute in above reaction
(10⁻⁴)[H⁺] = 10⁻¹⁴
multiplying both sides by 10⁴ to get the [H⁺]
[H⁺] = 10⁻¹⁰
To find the pH:
pH = -log[H⁺]
pH = -log(10⁻¹⁰)
pH = 10
The pH of a solution with OH - is 4.30
pH is an index to describe the concentration of hydronium ions. Mathematically, pH is described as:
pH=−log[H3O+]
we have to know that the product of the concentration of hydroxide and hydronium ions in a solution will always equal 10−14 at 24oC.
Mathematically it is written as:
[H3O+][OH−]=10^−14
Taking the negative log of both sides:
pH+pOH=14
pH=14−pOH
Given pOH=2.0×10−10
pH=14−(−log10(2.0×10−10)
pH=4.30
