11 Questions
What is the Arrhenius concept of acids and bases?
Acids give H+ ions in water, bases give OH ions in water.
Give an example of a base that is corrosive in concentrated form.
Sodium hydroxide (NaOH)
What is the Latin origin of the word 'acid' and what does it mean?
The Latin word is 'Acidus' meaning sour.
What is the characteristic property of acids that allows them to be recognized?
Acids turn blue litmus red.
What is the role of an alkaline medicine in treating acidity?

Define Arrhenius acids and give an example.
Arrhenius acids are substances that dissociate in water to produce H+ ions. Example: Hydrochloric acid (HCl)
According to the Bronsted-Lowry theory, how are substances classified as acids or bases?
Substances are classified as acids if they donate protons and as bases if they accept protons.
Classify substances as Lewis acids or bases.
Lewis acids accept electron pairs, while Lewis bases donate electron pairs.
Write the equation for the self-ionization of water.
The equation is: $2H2O ightleftharpoons H3O+ + OH-$
Given the hydrogen or hydroxide ion concentration, classify a solution as neutral, acidic, or basic.
If the hydrogen ion concentration is equal to the hydroxide ion concentration, the solution is neutral. If the hydrogen ion concentration is greater, the solution is acidic. If the hydroxide ion concentration is greater, the solution is basic.
Complete and balance a neutralization reaction.
Example: $HCl + NaOH ightarrow NaCl + H2O$
