compare the way acids and bases were defined by boyle in the 1600s with the way they were defined by…

Brief Explanations:

Boyle described acids as substances with sour taste, ability to dissolve metals, turn blue - litmus red; bases as bitter, slippery, turn red - litmus blue. Arrhenius defined acids as substances that produce $H^+$ ions in water and bases as substances that produce $OH^-$ ions in water. Arrhenius's definition was supported by Boyle's as the properties Boyle observed could be related to the presence of $H^+$ and $OH^-$ ions. For example, the sour taste of acids could be due to $H^+$ ions and the basic properties like slippery feel could be related to the presence of $OH^-$ ions.

Answer:

Boyle's definitions were based on observable properties like taste, litmus - paper color change, and reaction with metals. Arrhenius's definitions were based on ion production in water. Arrhenius's definition was supported by Boyle's because the properties Boyle noted could be attributed to the ions Arrhenius proposed.
