Example Question #1 :Help With Acid Base Reactions
What volume of a 1.2M solution of hydrochloric acid is needed to neutralize 50mL of a 3M sodium hydroxide solution?
The equation to use here is:
Here,is the molarity of the acid,is the volume of the acid,is the molarity of the base, andis the volume of the base. Don't forget to convert the volume to liters!
Example Question #2 :Help With Acid Base Reactions
What kind of reaction is an acid-base neutralization reaction?
Double-replacement
Single-replacement
Decomposition
Addition (synthesis)
Oxidation-reduction
Double-replacement
Below is a generic acid-base neutralization reaction:
The products are always water, and a salt. This salt is produced from the resulting ionsand. Thefrom the acid replaces thefrom the base, and thefrom the acid replaces thefrom the base. Since there are two replacements, acid-base neutralizations are classified as double-replacement reactions.
Example Question #3 :Help With Acid Base Reactions
Which of the following is the definition for an Arrhenius acid?
None of these
A substance that increases theconcentration when added to water.
一个原型n donor
一个原型n acceptor
A substance that increases theconcentration when added to water
A substance that increases theconcentration when added to water
Arrhenius acid/base theory was created by Swedish chemist Svante Arrhenius, and is the oldest acid/base classification. According to his classification, acids are compounds that increase the concentration ofions in a solution, while bases are compounds or elements that either decrease the concentration ofions in solution or increase the concentration ofions in a solution. The other two answers describe the Brønsted–Lowry theory of acids and bases.
