Indicate whether each of the following compounds dissolves in water to give ions, molecules, or both. 1. NaCl
2. HF
3. CH3CH2OH (ethanol)
4. HI
5. Weak electrolyte
6. Nonelectrolyte
7. Strong electrolyte

The answer is in the explanation

Explanation:

An ion is defined as a particle that is positive or negative charged.

In water, strong electrolytes dissociates completely to produce ions. Weak electrolytes dissolves partially. One part in ions and the other still as the complete molecule. A nonelectrolyte doesn't dissociates in any way!

1. NaCl . STRONG ELECTROLYTE.  Dissociates in ions

2. HF . WEAK ELECTROLYTE. Dissociates partially producing both molecules and ions

3. CH3CH2OH (ethanol) . NONELECTROLYTE. Doesn't dissociates producing just molecules.

4. HI . STRONG ELECTROLYTE. Dissociates completely in ions.

5. Weak electrolyte . Dissociates partially giving ions but also molecules

6. Nonelectrolyte . Only give molecules.

7. Strong electrolyte. Gives only ions.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
