Question
1. Why is it important that all the glassware or equipment used must be thoroughly with deionized water? 2. What does it mean to saturate a solution, and how will this affect an observation of solubility? 3. Break the following compounds into their respective ions: a. Na CO, b. NH,CI c. MgSO 4. Write the balanced molecular equation, ionic equation, and net ionic equation for the following combinations. Be sure to include its physical state as (aq), (s), (1) or (g). a. Silver nitrate sodium chloride b. Magnesium carbonate +hydrochloric acid c. Barium nitrateammonium sulfateExplanation / Answer
Q1
deionized water does not contains ions, recall that ions in solution are common, depending on the tap water used
CO3-2, H+/OH-; Mg+2, Ca+2, and Na+, K+ are very common ions impurities which can affect our balanced
Q2.
sautrate solution --> addition of salt/species until no furhter amount can be dissolved in the solvent / typically water)
Q3
a
Na2CO3 = 2Na+ and CO3-2
b
NH4Cl --> NH4+ and Cl-
c)
MgSO4 --> Mg+2 + SO4-2
