WHAT???? which of these are electrolytes??
CH3CH2OCH2OH
PCl3
Na2CO3
O2
If they dissociate they are electrolytes. Na2CO3 yes. O2 no
To determine which of these substances are electrolytes, we need to understand what electrolytes are. Electrolytes are substances that can conduct an electric current when dissolved in water or in molten form. This conductivity occurs because electrolytes dissociate into ions when dissolved or melted, allowing the electric current to pass through the solution.
Now let's examine each of the substances you've mentioned:
1. CH3CH2OCH2OH: This is a molecular compound known as ethylene glycol. Molecular compounds typically do not dissociate into ions when dissolved in water, so they are not electrolytes.
2. PCl3: This is a covalent compound called phosphorus trichloride. Similar to molecular compounds, covalent compounds do not dissociate into ions in water, so they do not act as electrolytes.
3. Na2CO3: This is a compound called sodium carbonate. Sodium carbonate dissociates into ions (Na+ and CO3^2-) when dissolved in water, making it an electrolyte.
4. O2: This is the molecular formula for oxygen gas. Like other molecular compounds, oxygen does not produce ions when dissolved in water, so it is not an electrolyte.
Therefore, the only substance among the options provided that is an electrolyte is Na2CO3.
