pH (potential of hydrogen) is a physical quantity which allows us to measure the acidity or basicity of a solution.
--if the pH<7 the solution is acidic (more H+ ions)
--if the pH=7 the solution is neutral (H+=HO-)
--if pH>7 basic solution (more HO- ion)

Mathematics, Physics & Programming Tutorials, High School + UndergraduatesAre you a high school or high school student and have difficulty understanding and solving math or physics problems? Then I am someone who would like to help you with that. I often see that in standard classroom teaching is succinctly taught. As a result, the student misses out on the whole picture, making the teaching material and the problems vague and unclear. My goal is to take the time for each student to complete the whole picture and guide them through complex problems, so that the student can not only take tests and exams with ease, but also enjoy learning the material.
