The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 0, that means that the concentration of H+ is equal to 1 molar, because -log(1) = 0. If you have a 1 M solution of any strong acid, the pH will be equal to zero.
Whether something is acid or base the strength of that solution is measured by the pH scale. 0 (zero) is the most acid and 14 is the most base. distilled water measures 7 and is completely neutral. Ammonia is an example of a base and is usually measured at a pH of 11.6. So the answer to your question is that an acid has a positive pH. There is no such thing as a negative pH.
If by pH you mean the acidity of a compound then by combining equal amounts of each pH they would all "cancel each other out" i.e. neutralise which leaves a pH of 7
How do you find pH of a solution with no indicator? Well if you don't want to use pH meter, the only other way to find out is using the pH paper which turns into different colours respectively to the pH of the solution, that is not too accurate,...
You need to determine the percent of hydrogen (pH) molecules in the solution.
It means that its an Acid. pH < 7 is acidic. pH > 7 is basic. pH = 7 is neutral.
No. pH is a log scale. You can't have a pH of zero. ---- Above answer left in to correct a misconception. Yes, you certainly can have a pH of zero. A 1 molar solution of a strong acid has a pH of zero, and stock HCl (roughly 12 molar) has a pH of about -1.1 or so. pH is the negative log of the hydrogen/hydronium ion concentration, which for a strong acid is approximately the same as the acid concentration. The log of 1 is zero, therefore the pH of a 1 molar solution of a strong acid is zero. The log of 10 is 1, therefore the pH of a 10 molar solution of a strong acid is -1.
Strongly Acidic
3,2,1 and zero, closer to the zero is more acidic solution.
Its pH is 3
yes. because the ph of a neutrasl solution is 7. Meaning, the pOH of the solution is 7 7=7
It should be between 2-5 in the ph scale if dissolved in water
Standardize the pH meter using a buffer solution of known pH value.Basically take buffer of pH value 4.Then set zero reading in the pH meter.Now remove unknown buffer solution.(take care with atmospheric temperature.)
It depends what you mean by water solution. If it's a solution of something else in water, it depends on the solute. If you mean just water, it's pH 7.
It is a neutral solution, pH = 7.0 at room temp.
The pH is define in the following way: pH = -log [H+] What that means is the pH is the negative of the base 10 logarithm of the concentration of hydrogen ions in the solution. So, if you have a pH = 8, that means that the concentration of H+ is equal to 1*10-8 molar, because -log(1*10-8) = 8.And 1*10-8 is equal to 0.00000001, and so if the concentration of H+ is equal to 0.00000001 M, than the pH of the solution is 8 However, a solution with pH = 8 is considered BASIC, not acidic. If the pH is less than 7, it is acidic. If the pH = 7, the solution is neutral, and if the pH is greater than 7, it is considered basic.So the numbers are correct, but the solution is not called acidic.
pH level is a short term for "Potential Hydrogen" The pH of any solution is the measure of its hydrogen-ion concentration. The higher the pH reading, the more alkaline and oxygen rich the fluid is. The lower the pH reading, the more acidic and oxygen deprived the fluid is.
