Question 10 (1 point) All acids and bases must be dissolved in water for them to be corrosive Question 10 options: True False Question 11 (1 point) A strong base has a very high pH Question 11 options: True False

Consider the following statements, choose the incorrect one:1 point[A]. The strong bases (or alkalis) such as sodium hydroxide are also very corrosive, and attack and destroy our skin.[B]. An acid is a substance which dissociates on dissolving in water to produce hydrogen ions.[C]. The compounds such as glucose and alcohol also contain hydrogen but they do not show acidic character.[D]. Only sulphuric acid and hydrochloric acid solution conducts electricity.

List two properties of acids and two properties of bases.

13 Which statement about acids and bases is always correct?A An acid with two H atoms per molecule will be stronger than an acid with one H atom permolecule.B A concentrated solution of a strong acid will have a lower pH than a dilute solution of a weakacid.C A concentrated solution of a strong base will have a lower pH than a dilute solution of a weakbase.D A strong acid is more dissociated in solution than a strong base

All of the following statements can be used to describe a base/basic solution EXCEPT:Group of answer choicesBases are commonly used as household cleaners.Bases produce OH- ions in water.Bases are electron pair acceptors.A basic solution has a pH value greater than 7.A strong base dissociates completely into ions when dissolved in water.
