The hydrogen ion concentration of milk is about 1.6*10^-7 moles per liter. Find the pH.
Is your subject possibly chemistry?
It is actually for an Intermediate Algebra class. Logitharims.
pH = -log(H^+)
To find the pH, we can use the formula:
pH = -log[H+]
where [H+] represents the hydrogen ion concentration.
Given that the hydrogen ion concentration of milk is about 1.6 * 10^-7 moles per liter, we can substitute this value into the formula:
pH = -log(1.6 * 10^-7)
To calculate the pH using this formula, we need to take the logarithm of the hydrogen ion concentration and then change the sign.
1. Start by taking the logarithm of 1.6 * 10^-7 using a calculator. The result is -6.79588.
2. Change the sign, so the pH becomes 6.79588.
Therefore, the pH of the milk is approximately 6.80.
