the ph scale is used to measure?

Answer 1

How acid or alkaline something is. Specifically, it measures the concentration of H+ (acid) ions via
pH = -log [H+]
where the square brackets indicate concentration, as is usual in chemistry.
Water tends to dissociate a tiny little bit into H+ and OH- ions. Thus, neutral water has 1.0 * 10^-7 mol/L of each of these. That is why the pH of a neutral solution is 7. A higher concentration of H+ ions means a more acid solution and gives a lower pH. A lower concentration of H+ ions means an alkaline solution and gives a higher pH. Note that negative pH is possible for concentrated acids.

Answer 2

The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.

Answer 3

The Ph scale (Ph stands for potential hydrogen) measures the acidity or basic-ness of any substance.

It goes from 1-14. Anything close to 1 (1-7) is an acid. The most acidic is hyrdochloric acid, found in the tummy.

From 7-14, those are bases.

Seven is neutral, and it is water.

Answer 4

The PH scale is used to measure the acidity or alkalinity of a solution

Answer 5

pH scale is used to measure the acidity of different substances, in terms of activity of hydrogen (or how many protons or H+ are donated in a solution), and is a reverse logarithmic representation of relative hydrogen proton (H+) concentration. Theory says that an acid (HA) is a substance that donates H+ in an aqueous solution. An acid disolved in water gives a solution with pH less then 7. Aqueous solutions with pH values lower than 7 are considered acidic, while pH values higher than 7 are considered basic. pH is dimensionless.
