Question
Some chemical compounds are listed in the first column of the table below. Each compound is soluble in water.Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. The important chemical species that would be present in this solution are written in the second column of the table. Use the checkboxes to classify each compound.compound important species presentwhen dissolved in water type of compound (check all that apply)ionic molecular strong acid weak acid strong base weak baseHC2H3O2 H3O+,C2H3O−2,HC2H3O2,H2O CH3NH2 CH3NH+3,OH−,CH3NH2,H2O KNO3 K+,NO−3,H2O NaOH Na+,OH−,H2O
Solution
The table can be classified as follows:
-
HC2H3O2: This is acetic acid, a weak acid. So, the checkboxes for 'molecular' and 'weak acid' should be checked.
-
CH3NH2: This is methylamine, a weak base. So, the checkboxes for 'molecular' and 'weak base' should be checked.
-
KNO3: This is potassium nitrate, a salt of a strong acid and strong base. It is an ionic compound. So, the checkbox for 'ionic' should be checked.
-
NaOH: This is sodium hydroxide, a strong base. It is also an ionic compound. So, the checkboxes for 'ionic' and 'strong base' should be checked.

Complete the table by filling in the name or chemical formula of each compound, whichever is missing. (If there is more than one way to name the compound, choose the name used when the compound is dissolved in water.)
