pH of strong acid or base does not depend upon temperature. pH of weak acid decreases with increase in temperature due to increase in ionization. pH of weak base increases with increase in temperature due to increase in ionization or [OH-] ion concentration. ...
Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. Th
Substances can be classified as acidic, basic, or neutral. The pH scale ranges from 0 to 14. The pH of an acid is below 7 and a base is above 7. Anything that has a pH of 7 is classified as neutral. Common household items such as vinegar and bleach give us a clue about the mol...
Take the cabbage juice in 5 separate cups mixed it with 5 different liquids, (ex: coke, milk, cleaning agent, etc,) and matched the color to a pH chart to tell if it was a base or an acid. Give a simple explanation of what chemical changes occurred to tur ...

Litmus and pH paper contain a chemical that changes color as it makes contact with an acid or base. The paper will turn red in acids and blue in bases. Usually a color chart is provided with the pH paper in order for the user to determine the pH range of the indicator. Using paper ...
pH isa measure of how acidic or basic achemicalis when it's inaqueous (water) solution. A neutral pH value (neither an acid nor a base) is 7. Substances with a pH greater than 7 up to 14 are considered bases. Chemicals with a pH lower than 7 down to 0 are consideredacids. The ...
the lower the number, the more acidic a substance is. Water, for example, has a pH of 7 and is considered neutral (neither acid nor base). You can determine the pH of a chemical by using a pH indicator strip and checking the strip's color to a pH chart. For fun, measure the pH...
Acid–Base (pH) Control Newer-model fluid-delivery systems will not go into conductivity if the pH is too high or too low. However, the majority of dialysis clinics perform independent pH tests before each dialysis. Fluid delivery machines using bicarbonate dialysate may or may not have pH mon...
