Activity $2$:

$>$ To check the electrical conductivity for certain substances. A student used a conductivity apparatus equipped with a light bulb. Her observations are listed in the table below: Complete the table:

Activity $3$:

Write the ionization reaction for the following salts, acids, and bases showing all the ions formed. $($p$.$s$.$ consider the salts to be highly soluble in water.$)$

Hint:

break each substance into its ions that will form when dissolved in water.

Use the periodic table to find the charges of ions$/$polyatomic ions.

$HN{O}_3$

$A{l}_2(S{O}_4{)}_3$

$N{H}_3$

$K_{2}C{O}_3$
