Hello, I am having an issue with figuring the following: For pH 9.5 I am getting 3.16 x 10 ^-10. Is this correct? Thank you Solution X has a pH of 9.5, and solution Y has a pH of 7.6.? What is [H3O+] in Solution X? What is [H3O+] in Solution Y?

The acidity or alkalinity of a solution is defined by pH = –log[H+] where [H+] is the hydrogen ion concentration, measured in moles per liter. Solutions with a pH value of less than 7 are acidic; solutions with a pH value of greater than 7 are basic and solutions with a pH of 7 (such as pure water) are neutral. a) Suppose that you test apple juice and find that the hydrogen ion concentration is [H+] = 0.0003. Find the pH value and determine whether the juice is basic or acidic.

A solution is prepared by dissolving 50 grams of salt in 250 centimeter cube of water. Find the density of the solution [Take the density of water =1.0 gram per centimeter cube]
