Answer

Brief Explanations:

  1. Acids are characterized by a sour taste, not a bitter taste.
  2. Bases have a pH greater than 7, acids have a pH less than 7.
  3. A binary ionic compound is composed of a metal cation and a non - metal anion, not two metal cations.
  4. Magnesium phosphide ($Mg_3P_2$) is formed by the transfer of electrons from magnesium (metal) to phosphorus (non - metal), so it is an ionic compound.

Answer:

  1. B. False
  2. B. False
  3. B. False
  4. A. True
