The Hydronium Ion Concentration in a Glass of Red Wine

What is the hydronium ion concentration in a glass of red wine with a pH of 3.65?

The pH of a glass of red wine is found to be 3.65, the hydronium ion concentration in this glass of wine is approximately 2.8 x 10^(-4) M.

Calculating Hydronium Ion Concentration in Red Wine

The pH of a glass of red wine is measured to be 3.65. The pH scale is a measure of acidity or basicity of a solution, with values ranging from 0 to 14. A pH of 3.65 indicates that the solution is acidic. To determine the hydronium ion concentration in this glass of wine, we can use the equation: pH = -log[H3O+].

First, we need to rearrange the equation to solve for [H3O+]. This can be done by taking the antilog of both sides of the equation: 10^(-pH) = [H3O+].

Now, let's plug in the given pH value of 3.65 into the equation: [H3O+] = 10^(-3.65). Using a scientific calculator, we find that 10^(-3.65) is approximately 2.8 x 10^(-4) moles per liter.

Therefore, the hydronium ion concentration in a glass of red wine with a pH of 3.65 is approximately 2.8 x 10^(-4) M (moles per liter). This means that there are 2.8 x 10^(-4) moles of hydronium ions per liter of wine.
