Answer to Question #73507 in General Chemistry for Chloe Lozano

Question

Which of the following statements is true about acids?

A. Acids taste sour.
B. Acids conduct electricity when dissolved in water.
C. Acids turn blue litmus paper red.
D. Acids donate protons or H+ ions.
E. All of the Above

Answer 1

Answer: most acids taste sour, conduct electricity when dissolved in water, turn blue litmus
paper red, but not all of them. Some acids taste bitter, others sweet and some simply delicious.
Silicic acid is tasteless, is not soluble in water, does not conduct electricity, does not turn blue
lithmus paper red, since it merely does not dissociate in water. The only correct option, which
works for all Arrhenius acids is D. By a definition given by Svante Arrhenius, all acids donate
protons.
