Question
Label each of the following ions as cations or anions a. Sodium: b. Chloride: c. Sulfate ion: d. Ammonium ion: e. Magnesium ion: f. Nitrate ion: g. Phosphate ion: 2. Label each of the following solutions as either an electrolyte/ionic solution or non-electrolyte solution. a. Barium chloride solution: b. Hexanol (alcohol) solution: c. Iron(II) oxide solution: d. Aluminum chloride solution: e. Acetic acid (vinegar): 3. Name the following compounds: a. KNO_3: b. BaSO_4: c. Ca_3(PO_4)_2: d. Mg(OH)_2: e. LiCl: f. NH_4Br: 4. Circle the ions that are responsible for producing hard water: a. Barium b. sodium c. Lithium d. calcium e. lead f. magnesium g. carbon h. nitrogen 5. Write the net ionic equation for the reaction of barium chloride reacting with sodium sulfate. 6. When 0.015 grams of sodium sulfate is dissolved in 200 mL of water, what is the concentration of the ions expressed in parts per million (ppm)/Explanation / Answer
An anion is an ion that has gained one or more electrons, attaining with negative charge. Like when Cl atom gain one 1 e it is converting anion Cl-
A cation is an ion that has lost one or more electrons, attaining with positive charge. Like when Sodium lost one electron and converted into Na+.
Sodium: Na + cation
Chloride Cl- anion
Sulfate ion SO4^2- anion
Ammonium ion NH4 ^+ Cation
Nitrate ion NO3^-1 anion
Phosphate ion PO4^3- Cation.
2. a , BaCl2, is a strong electrolyte
hexanol is a non-electrolyte
Iron (II) oxide solution is a strong electrolyte
AlCl3, is a strong electrolyte
Acetic acid a non-electrolyte
3.
KNO3: Potassium Nitrate
BaSO4: Barium Sulfate
Ca3(PO4)2 Calcium Phosphate
Mg(OH)2 Magnesium hydroxide
LiCl: Lithium chloride
NH4Br Ammonium Bromide
Hard water is a type of water that contains doubly charges cations such asCa2+ and Mg2+ .
Thus the answer is Ca2+ and Mg2+
