Question

1. for each compound (all water soluble), would you expect the resulting aqueous solution to conduct electrical current? a. cscl b. ch3oh c. ca(no2)2 d. c6h12o6

Explanation:

Step1: Recall conductivity concept

Conductivity in aqueous solutions is due to the presence of ions. Ionic compounds dissociate into ions in water and conduct electricity, while covalent compounds that do not ionize do not conduct well.

Step2: Analyze CsCl

CsCl is an ionic compound. In water, it dissociates into $Cs^+$ and $Cl^-$ ions. So the solution will conduct electricity.

Step3: Analyze $CH_3OH$

$CH_3OH$ is a covalent compound. It does not dissociate into ions in water to a significant extent. So the solution will not conduct electricity well.

Step4: Analyze $Ca(NO_2)_2$

$Ca(NO_2)_2$ is an ionic compound. In water, it dissociates into $Ca^{2 + }$ and $2NO_2^-$ ions. So the solution will conduct electricity.

Step5: Analyze $C_6H_{12}O_6$

$C_6H_{12}O_6$ (glucose) is a covalent compound. It does not dissociate into ions in water to a significant extent. So the solution will not conduct electricity well.

Answer:

a. Yes
b. No
c. Yes
d. No
