Which compounds are both classified as electrolytes?
A.
NH4Cl and KCl
B.
KCl and CH3OH
C.
NH4Cl and C6H12O6
D.
C6H12O6 and CH3OH
A. NH4Cl and KCl
To determine which compounds are classified as electrolytes, we need to determine if they can conduct electricity when dissolved in water. Electrolytes are compounds that dissociate into ions in water and therefore allow the flow of electric current.
A. NH4Cl and KCl: Both NH4Cl (ammonium chloride) and KCl (potassium chloride) are soluble salts that dissociate into ions in water. They are classified as electrolytes.
B. KCl and CH3OH: CH3OH (methanol) is a covalent compound and does not dissociate into ions in water. It is not classified as an electrolyte. Therefore, only KCl is an electrolyte in this option.
C. NH4Cl and C6H12O6: C6H12O6 (glucose) is a covalent compound and does not ionize in water. It is not classified as an electrolyte. Therefore, only NH4Cl is an electrolyte in this option.
D. C6H12O6 and CH3OH: Both C6H12O6 (glucose) and CH3OH (methanol) are covalent compounds and do not dissociate into ions in water. Neither of them is an electrolyte.
So, the correct answer is A. NH4Cl and KCl.
To determine which compounds are classified as electrolytes, we first need to understand what an electrolyte is. Electrolytes are substances that can conduct electricity when dissolved in water or melted. They exist as ions in solution and can carry electric charge.
To find out if a compound is an electrolyte, we can consider its ability to dissociate into ions when it is dissolved in water.
Let's analyze each option:
A. NH4Cl and KCl
NH4Cl is ammonium chloride, and KCl is potassium chloride. Both of these compounds are ionic compounds and readily dissociate into ions when dissolved in water. Therefore, NH4Cl and KCl are classified as electrolytes.
B. KCl and CH3OH
KCl, as mentioned before, is an ionic compound and is a strong electrolyte. On the other hand, CH3OH is methanol, which is a covalent compound and does not dissociate into ions in solution. Therefore, CH3OH is not classified as an electrolyte.
C. NH4Cl and C6H12O6
We already established that NH4Cl is an electrolyte. C6H12O6 is glucose, which is a covalent compound and does not dissociate into ions in solution. Therefore, C6H12O6 is not classified as an electrolyte.
D. C6H12O6 and CH3OH
Both C6H12O6 and CH3OH are covalent compounds and do not dissociate into ions in solution. Therefore, neither C6H12O6 nor CH3OH are classified as electrolytes.
In conclusion, the compounds classified as electrolytes are NH4Cl and KCl, which are found in option A.
