The concept of pH was first introduced by Danish chemist Søren Peder Lauritz Sørensen at the Carlsberg Laboratory in 1909. Sørensen suggested the notation "PH" for convenience, standing for "power of hydrogen", using the cologarithm of the concentration of hydrogen ions in solution, p[H]
pH 1 is the most acidic, as it is closest to 0 on the pH scale. Lower pH values indicate higher acidity.
You can test the pH of a solution using pH strips, pH meters, or pH indicator solutions. With pH strips, you simply dip the strip into the solution and compare the color change to a pH color chart. pH meters provide a digital pH value by immersing the electrode into the solution. pH indicator solutions change color based on the pH of the solution, allowing for a visual estimation of pH.
To measure pH accurately in a solution, you can use a pH meter or pH strips. A pH meter provides a digital reading of the pH level, while pH strips change color based on the pH level of the solution. Simply dip the pH meter probe or pH strip into the solution and read the pH value indicated.
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
The lower the pH, the more acidic the solution is. Remember, pH 7.0 is H2O. As pH decreases below 7, the solution's acidity increases. As pH increase above 7, the basicity of the solution increases. Hence, in the choices you provided, pH 1.0 is most acidic.
It is not a discovery - it is a chemical concept.
no one he was the first to discover it , at least that is what it says in PH history
The first recorded acid rain "storm" was in 1944 when readings of pH 2.4(as acidic as vinegar) were recorded during storms in New England.
first tell me what pH is pH, for those of us who skipped grade school science class and haven't discovered Google, is the level of acidity or alkalinity of a solution. The scale ranges from 0 (highly acidic) to 14 (highly alkaline). Pure water, which is neither acidic nor alkaline, has a pH of 7. To answer the original question, pineapple juice, has a pH of 3, about the same as orange juice.--tw2

pH=6,4

"pH of a liquid" means "the negative of the logarithm to the base 10 of the activity of electrically mobile positive hydrogen ions in the liquid." For most purposes, the "activity" is close to the molar concentration, but in very concentrated acids, a correction factor for the molar concentration called the "activity coefficient" is needed to account for the fact that the average effect of a single mobile positive hydrogen ion is not quite as strong in a very concentrated liquid (an analogy to the economic "law of diminishing returns"). In aqueous solutions, the mobile positive hydrogen ions are generally written in chemical equations as "H+ (aq)" or "H3O+".

The pH is determined with a pH-meter.
