percent purity could simply mean the whole percent which is a 100%?

If pKa is greater than pH then what percent is ionized?

If pKa is greater than pH, then the percent ionization will be very low, usually less than 1%. This is because at high pH values, the majority of the compound will exist in its non-ionized form.


Why percent yield is more than 100?

Percent yield greater than 100% can occur due to impurities in the final product, incomplete reactions, or errors in the measurements taken during the experiment. It is a sign that not all of the reactants were converted to the desired product, leading to a higher yield than theoretically expected.


Is the percent by mass of copper in CuSO4  5H2O the same as in CuSO4?

No, the percent by mass of copper in CuSO4  5H2O will be different than in CuSO4 because CuSO4  5H2O includes water molecules in addition to the copper sulfate compound itself. Therefore, the total mass of CuSO4  5H2O will be greater, resulting in a lower percent by mass of copper in CuSO4  5H2O compared to CuSO4.


What Electronegativity difference will result in a bond with 50 percent ionic character?

An electronegativity difference greater than 1.7 will result in a bond with approximately 50 percent ionic character. This is based on the general guideline that a difference in electronegativity greater than 1.7 indicates a predominantly ionic bond between two atoms.


Which pair CU and CI or I and CI would have a bond with a greater percent ionic character?

Cu-Cl is more ionic than I-Cl as the difference in the electronegativity is more in the case of Cu and Cl.
