in a solution of pH of 3.26, the molar concentration of the hydronium ion is ?
pH = -log(H^3O^+)
Substitute and solve for H3O^+.
To determine the molar concentration of the hydronium ion in a solution of pH 3.26, we need to understand the relationship between pH and molar concentration.
1. The pH scale measures the acidity or alkalinity of a solution. A pH value below 7 indicates acidity, while a pH value above 7 indicates alkalinity.
2. The pH value can be calculated using the equation: pH = -log[H+], where [H+] represents the concentration of the hydronium ion in moles per liter (Molarity, M).
3. To find the molar concentration of the hydronium ion, we need to rearrange the equation as follows: [H+] = 10^(-pH).
Now, let's calculate the molar concentration of the hydronium ion:
[H+] = 10^(-pH)
= 10^(-3.26)
≈ 4.75 x 10^(-4) M (rounded to four significant figures)
Therefore, the molar concentration of the hydronium ion in a solution with a pH of 3.26 is approximately 4.75 x 10^(-4) M.
