SUMMARY

The discussion centers on determining the molecular and net ionic equations for the reactions of sodium carbonate (Na2CO3) with magnesium bromide (MgBr2) and magnesium sulfate (MgSO4) with sodium hydroxide (NaOH). Participants note that while all compounds are generally soluble, the presence of weakly soluble products leads to observable reactions. Specifically, the discussion highlights the importance of recognizing exceptions in solubility rules, which can lead to confusion when predicting reactions.

PREREQUISITES
  • Understanding of molecular equations and net ionic equations
  • Familiarity with solubility rules in aqueous solutions
  • Knowledge of weakly soluble compounds, such as magnesium hydroxide (Mg(OH)2) and calcium carbonate (CaCO3)
  • Basic chemistry concepts related to ionic compounds and reactions
NEXT STEPS
  • Research the solubility rules for ionic compounds in water
  • Learn how to write net ionic equations for double displacement reactions
  • Study the properties and reactions of weakly soluble salts
  • Explore examples of precipitation reactions in aqueous solutions
USEFUL FOR

Chemistry students, educators, and anyone interested in understanding precipitation reactions and solubility in aqueous solutions.

Write the molecular eqaution and the net ionic equation for each of the following aqueous reactions. If no reaction occurs, write NR after the arrow.

A) Na2Co3 + MgBr2--->
B)MgSO4 + NaOH---->

I can't figure these two out. From the solubility rules, all the compounds are soluble so there shouldn't be a reation but the answer in the back of the book shows a reaction.

What am I doing wrong?

Solubility is not 0/1 - substance is either soluble or insoluble. All salts are soluble, just some more and some less. Depending on where do you put the border between those that will be classified as soluble and insoluble rules will be slightly different.

However, there are two weakly soluble products of these reactions - two that I beleve should be listed in most solubility rules tables.
