What happens to the pH of a solution when the concentration of H+ ions increases?
The pH decreases
Which of the following is a strong acid?
Hydrochloric acid (HCl)
A substance that releases hydrogen ions in water is called an ______
acid
A compound formed by the neutralization reaction between an acid and a base is called a ______
salt
A substance that releases hydroxide ions in water is called a ______
base
What is the difference between a Lewis acid and a Brønsted-Lowry acid?
A Lewis acid accepts a pair of electrons, while a Brønsted-Lowry acid donates a proton.
Explain the concept of amphoteric substances and provide an example.
Amphoteric substances can act as both acids and bases, depending on the reaction conditions. An example is water, which can donate a proton (acting as an acid) in the presence of a stronger base, or accept a proton (acting as a base) in the presence of a stronger acid.
Discuss the formation of a salt and explain why it is considered a neutral compound.
A salt is formed by the reaction between an acid and a base, where the hydrogen ion of the acid is replaced by a metal cation. Salts are considered neutral compounds because they do not affect the pH of a solution when dissolved in water.
Test your knowledge on acids, bases, and salts with questions about pH of neutral solutions, strong acids, and the relationship between H+ ion concentration and pH levels.
