Question

which statement best compares acids and bases? 10 points a. acids are not corrosive, bases are very corrosive b. acids and bases are both conductors of electricity c. acids have high ph, bases have low ph d. acids react with bases, but bases do not react with acids students find that a solution conducts electricity and is corrosive. what 10 points additional test would best identify if it’s an acid or base? a. measure its density b. measure its freezing point c. determine its ph d. determine its transparency water is neutral because it has equal amounts of hydrogen and * 10 points hydroxide ions. which statement is true about acids and bases? a. acids produce more hydrogen ions, bases produce more hydroxide ions b. acids produce more hydroxide ions, bases produce more hydrogen ions c. acids and bases both produce hydrogen ions d. bases produce more hydrogen ions than acids

Explanation:

First question:

Acids and bases are electrolytes. They dissociate in water to form ions, which can conduct electricity. Acids are corrosive, bases can be too. Acids have low pH, bases high pH, and they react with each other in neutralization reactions.

Second question:

pH is a measure of the hydrogen - ion concentration in a solution and is used to distinguish between acids (pH < 7), bases (pH > 7) and neutral substances (pH = 7). Density, freezing point and transparency are not relevant for this distinction.

Third question:

Acids increase the hydrogen - ion concentration in a solution, while bases increase the hydroxide - ion concentration.

Answer:

1. B. Acids and bases are both conductors of electricity
2. C. Determine its pH
3. A. Acids produce more hydrogen ions, bases produce more hydroxide ions
