Acid-Base Equilibria Review Practice Exam 2024. Bronsted-Lowry theory of an acid? - correct answer An acid is a substance which can donate a proton (H+) to a base. Bronsted-Lowry theory of a base? - correct answer A base is a substance which can accept a proton (H+) from an acid. (N.B. All bases must have at least one pair of electrons to be able to accept a proton. T/F: When an acid loses a proton to a base, it forms a base itself. - correct answer True. Similarly, when a base accepts ...

A student prepares a solution of calcium nitrate by reacting dilute nitric acid, HNO3, with the base calcium hydroxide, Ca(OH)2. (i) Why is calcium nitrate an example of a salt? ֎ -:- The H+ ion in a nitric acid has been replaced by a metal ion OR by a Ca2+ ion MCl2.2H2O is a salt with water of crystallisation, and M is a metal. the water of crystallisation makes up 22.2% by mass of the hydrated salt. What is the relative formula mass of the anhydrous salt? ֎ -:- 126 Strontium reac...
