Compute the molar solubility of Hg2Cl2 a solution that contains 0.0100M KN03 and is saturated with HG2Cl2(s)
how does direct current break apart water molecule? Does the DC current fill the outer shell full of electrons making a weaker attraction so hydrogen seperates from oxygen?
When measuring the boiling point of a compound, why is the micro boiling point determined at the point when the last bubble has left the bottom of the bell and the liquid begins to rise in the bell
Determine the absolute error and relative error in ppm CaCO3 associated with a single standardization and titration of an unknown CaCO3 solution
The wall of the flask is periodically rinsed with the previously boiled, deionized water from the wash bottle. How does this titrimetric technique affect the reported percent acetic acid in the vinegar. Explain.
HF is a stronger acid than HBR because F has greater electronegativity than Br 2) the acid (HA) strength will increase when the H-A bond strength increases
