What is the pH of a solution with (H3O+)=5.6x10-2M?
balu736 [363]

Answer:

Explanation:

Given parameters:

Concentration of H₃O⁺  = 5.6 x 10⁻²M

Solution:

To solve for the concentration of H₃O⁺ in the solution, we simply use the expression below:

            pH = -log₁₀[H₃O⁺]

where [H₃O⁺] =  5.6 x 10⁻²M is the concentration of H₃O⁺

            pH = -log₁₀[5.6 x 10⁻²] = - x -1.25 = 1.25

Phosphorylation

Explanation:

Phosphorylation is the term used to describe the transfer of a phosphate group (PO34-) from a donor to a receptor molecule or compound. The process of phosphorylation is usually catalysed by a biological enzyme called KINASE.

Phosphorylation can either be addition of an inorganic phosphate to a molecule. For example, addition of phosphate group to ADP to form ATP, or the donation of a phosphate group to another molecule, e.g transfer of phosphate from ATP to glucose to form glucose-6-phosphate during glycolysis.
