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
An equal volume of solution with a pH of 6 will have fewer hydrogen ions compared to a solution with a pH of 3. This is because pH is a logarithmic scale, so each unit change in pH represents a 10-fold change in hydrogen ion concentration.
A more acidic pH refers to a lower pH value on the pH scale, below 7. It indicates a higher concentration of hydrogen ions in a solution, making it more acidic.
Yes, for a neutral solution at room temperature, the pH and pOH values would be equal. Both would be around 7 due to the presence of equal concentrations of H+ and OH- ions in the solution.
The pH of a neutral solution with equal concentrations of H+ and OH- ions is 7. This is because the concentration of H+ ions equals the concentration of OH- ions in a neutral solution, resulting in a pH of 7.
A solution with a pH of 7.0 is considered neutral. It means that the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-) in the solution. Water at room temperature has a pH of 7.0.
A neutral solution has an equal concentration of H+ and OH- ions. At room temperature, this corresponds to a pH of 7 on the pH scale.
It should be between 2-5 in the ph scale if dissolved in water
A solution containing equal numbers of hydrogen ions (H+) and hydroxide ions (OH-) is a neutral solution with a pH of 7. This type of solution is also known as a neutral solution or pure water.
The concentration of hydroxide ions in a solution is related to the pH of the solution, but they are not exactly equivalent. The pH of a solution is a measure of the concentration of hydrogen ions, while the pOH is a measure of the concentration of hydroxide ions. The two values are related by the formula: pH + pOH = 14.
A pH of 7 indicates a neutral solution, where the concentration of hydrogen ions is equal to the concentration of hydroxide ions in the solution. This means that the solution is neither acidic nor basic.
