4. true
5. true
6. false

Answer 2

1.True, 2.True, 3.True, 4.True, 5.True, 6.False

Explanation:

1. Concentration of any solution is defined as the measure of solute dissolved in any particular amount of solvent. Some commonly used units to express concentration are percent composition, molarity, and mole fraction.
2. The addition of water to any solution increases the quantity of solvent and so decreases the solute concentration in specific amount of solvent because the number of moles is not changing but volume of water is increasing. So, the statement is true.
3. Vinegar with 5% acidity is considered to be diluted because percent acid is defined as the number of grams of acetic acid per 100 mL of vinegar. So the 5% vinegar in the stores has 5 grams of acetic acid per 100 mL.
4. Muriatic acid harmful as its expose to skin in its concentrated form can cause severe burns so it is diluted before using.
5. The statement is true as increased water content will slow down evaporation, and that will increase the surface contact time.
6. A solution with large amounts of solute is termed as concentrated solution. Diluted solutions have less amount of solute.
