WebNov 10, 2024 · Probably the most obvious property of acids and alkalis is that they change the pH of substances with which they are mixed. Acids change the pH value towards the acidic, alkalis shift into the alkaline (basic) range. This can be determined, for example, using litmus paper as an acid-base indicator (Fig. 13.1 ). WebMay 5, 2024 · acids mixed with bases make stronger acids Acids and bases interact with each other in what is called a neutralization reaction. The products of the reaction are a salt and water.
