Acids and salt assessment

1. Definitions and properties

a. Highlight which of the following is a basic oxide.

•Lithium oxide
•Aluminium oxide
•nitrogen dioxide

b. Define what is meant by a strong acid.

c. For the weak alkali ethyl amine, predict its likely pH (at 1 mol/dm), and the
colour it will turn universal indicator.

d. Explain two ways strong acids can be differentiated from weak acids without
the use of universal indicator.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
