Understanding Acids and Bases

What is the definition of an acid according to the Arrhenius theory?

• A substance that donates a proton in a reaction.

• A substance that increases the concentration of hydroxide ions in solution.

• A substance that increases the concentration of hydrogen ions in solution.

• A substance that accepts an electron pair.

Explain the difference between Arrhenius and Bronsted-Lowry definitions of acids and bases.

• Arrhenius defines acids and bases in terms of electron pairs, while Bronsted-Lowry defines them in terms of proton transfer.

• Arrhenius defines acids and bases in terms of proton transfer, while Bronsted-Lowry defines them in terms of electron pairs.

• Arrhenius defines acids as substances that increase hydrogen ions, while Bronsted-Lowry defines acids as proton donors.

• Arrhenius defines bases as substances that increase hydroxide ions, while Bronsted-Lowry defines bases as proton acceptors.

Describe how to calculate the pH of a solution given the hydrogen ion concentration.

• pH is calculated by taking the negative logarithm (base 10) of the hydrogen ion concentration.

• pH is calculated by taking the square root of the hydrogen ion concentration.

• pH is calculated by multiplying the hydrogen ion concentration by 10.

• pH is calculated by adding 7 to the hydrogen ion concentration.
