What are the characteristics of acids?

Back

Acids are corrosive substances with a strong smell, a sour taste, and a pH less than 7.

Front

What happens to the solubility of carbon dioxide gas (CO2) when the solvent is cooled?

Back

Cooling the solvent increases the solubility of carbon dioxide gas (CO2).

Front

What is the balanced equation for an acid-base neutralization reaction?

Back

NaOH + HCl → H2O + NaCl is the balanced equation for an acid-base neutralization.
