explain why soup precipitated when you added it to a saturated NaCI
Note that NaCl increases activity of species then, the ionic strength increases
NaCl will favour soap precipitation
Also note that soap might be formed of Na+ ions, therefore more reactant is present
both reaasons are enough to form soap precipitation
Why does PbF2 increase in solubility when acid is added to a saturated solution?
could you explain LeChatelier's principle

Explain why there is no reaction when sodium is added to a solution of methyllithium but when gallium is added to a solution of methyllithium, trimethylgallium is formed.
2.When concentrated H2SO4 (18M) is added to a saturated solution of sodium sulfate, a white precipitate is formed. Write a net-ionic equation for the equilibrium in saturated sodium sulfate, and explain the change in terms of Le Chatelier’s principle. 3.A solution contains the blood-red hexathiocyanatoferrate(III) complex ion, Fe(SCN)63-, in equilibrium with the iron(III) ion, Fe3+, and six thiocyanate ions, SCN-. If the solution is diluted with water, will the color deepen, fade, or stay the same? Why? In addition to...
Explain why the samples with larger amounts of solute precipitated at significantly higher temperatures than those with less solute. Discuss your answer in terms of the physical interaction between the solute and solvent.
Based on what you know about the structure of saturated and unsaturated fatty acids, explain why saturated fatty acids lead to cardiovascular disease, while unsaturated ones do not.
