Solubility Products, Common Ion Effect, Hardness of Water: Discussion, Conclusion, Safety Notes


Discussion
            In general, springily soluble with math formula of LeChatelier’s principle has been useful on salt solubles. A low soluble can be a dynamically equilibrium so its concentration on its ion is low.
            Express BaSO4 in math formula on LeChatelier’s Principle has main compunds the Barium and Sulfate

BaSO4 (s)  ยบ  Ba+2(aq)  + SO4-2 (aq)


The equilibrium expression for this reaction is:


 Since in a heterogeneous equilibrium the concentration of solid BaSO4 is a constant
for a given temperature, we can rewrite the expression as:


Ksp is called the solubility product constant.

            Many other has been issue on how soluble can be a sparingly soluble by modern gadget and equipment used. The solution is  Ca(OH)2 and the result is about small so its called sparingly soluble. Data shows how this happened and implies on mixing some concentration like NH3-NH4Cl solution in order to give better analysis on experiment. It solution can be determine the moles and its concentration calculations.  This data has substance of one mole Ca+2 and 2 moles OH-1 are present in solution.

The experiment also gives an idea of pertaining to the ph of substance that can be use if the solution is acidic or base. Some measurement as added like filtration paper in which some of its property like color has been change. PH indicator is good for detection how much acidic and base of substance is. This PH indicator for the measurement of [OH-1] in which it’s precisely measurement also th Ksp and the molar solubility. Ions have been added to solution to predict the molar solubility of said substances.

Conclusion

Hereby, this experiment has result, based on this the common ion was reduces the soluility of Sparingly Soluble Salt. We have 0.012 vs. 0.013. This agrees with LeChatelier’s principle.

Safety notes

On lab, always be ready for things, pls wear gloves cause substance can be irate skin, protect the eye, wear lab coat and be careful on chemical used. Don’t direct inhale near on experiment instead use mask for protection on do inhale and exhale near on experiment of chemistry. And be careful with indicator.
