Answers
Answer:
Three common methods:
pH paper strips (most simple) -drop a strip in the solution, and see the paper reflect a certain color. The color corresponds to the approximate pH of the solution.
pH meter-a calibrated meter with a probe in the solution can accurately read the pH of a solution
Indicator chemical-Phenolpthalein is the most common. It will turn pink in a basic solution, and remain clear in an acidic solution. This method does not tell you the pH. It only tells you if the solution is either basic or acidic.
Answer:
pH is a numeric scale in chemistry that is used to determine whether the substance is acidic, basic or neutral in nature. Substances that have a pH level of less than 7 are acidic in nature. For e.g Acidic substances such as vinegar, tamarind, lemon, etc. Substances that have a level of more than 7 are basic in nature
