Which of the following statements is true?a. Acids and bases cannot mix together. b. Acids and bases will neutralize each other. c. Acids, but not bases, can change the pH of a solution. d. Acids donate hydroxide ions (OH–); bases donate hydrogen ions (H+).

Respuesta :

Answer:

The answer is letter b.

Explanation:

a. Acids and bases cannot mix together. This is wrong, in fact there is a reaction called neutralization in which the reactants are an acid and a base.

b. Acids and bases will neutralize each other. This is true, when acids and bases react, the products are a salt and water and the reaction is called neutralization reaction.

c. Acids, but not bases, can change the pH of a solution. It's false, both acids and bases change the pH of a solution.

d. Acids donate hydroxide ions (OH–); bases donate hydrogen ions (H+). It's wrong, acids donate H+ and bases donate OH-.

The correct statement here is  Acids and bases will neutralize each other.

  • An acid can be explained as substance which can gives protons or one that can accepts a pair of valence electrons to form a bond

  • A base can be regarded as substance which can  take protons or substance which can give a pair of valence electrons when forming bond.

  • Acid and base cannot be be described as one that mix together,  though they can undergo what is called neautralization reaction.

  • Neutralization occurs when their is a reaction between acid and base whereby salt and water is been produced.

  • The statement in the questions which says that Acid but not base can bring change to PH of solution is not true this is because both the acid as well as the base brings change to the PH of solution.

  • An acid will donate H+ in a solution and base will give OH- in solution. I.e hydrogen ion and Hydroxide ion respectively
