A solution has a concentration of [H3O+] that is 0.04m. What is the pH of this solution? What is the pos?
pH = -log[H+] or -log[H3O+]
Given, [H3O+] = 0.04M
Now, pH = -log[0.04]
pH = -[-1.39]
pH = 1.39
From relation,
pH+pOH = 14
now, pOH = 14 - pH
pOH = 14 - 1.39
pOH = 12.61
A solution has a concentration of [H3O+] that is 0.04m. What is the pH of this...
What is the hydronium (H3O+) concentration of a solution with a pH of 12.22? What is the hydronium (H30+) concentration of a solution with a pH of 12.22?
The pH value is an expression of the molarity of H3O+ ions in solution. This concentration has strong impact on chemical reactions. The molarity is very small value, and therefore awkward to use. The pH scale simplifies this concentration making communication easier and faster. Demonstrate the relationship between pH and H3O+ molarity, using the formula, pH = -log(H3O+) where () indicates concentration in molarity of a substance. What is the pH of a solution, having the H3O+ concentration of 0.00038...
