If the original sodium tartrate solution had a concentration of 1.00 M instead of 0.100 M, what would the concentration of copper be in a solution created by combining 10 mL of it with 10 mL of the 0.100 M copper (II) sulfate solution.The Ksp is 1.37 x 10 ^-3
Here is the work i tried to do:CuSO4 is highly soluble so we know that it dissociates to Cu2+ and SO4 2- in equal amounts, 0.001moles Cu2+ and 0.001moles SO4 2-
for CuC4H4O6, Ksp = 0.0013 = [Cu2+][C4H4O6 2-] / [CuC4H4O6]0.0013 = x^2 / 1M - xx^2 + 0.0013x - 0.0013 = 0x = 0.036M Cu 2+
Calculate the molarity of an aqueous NaOH solution if 30.10ml of .500M H2SO4 is required to reach the end point when titrated against 10.00mL of NaOH solution.
if a solution 110 mL HBr has unknown concentration and is titrated with 80 mL of .150 M NaOH base soultion. Calculate the concentration of the HBr solution.
For the following amino acids, indicate how they might interact to contribute to the tertiary or quaternary structure of a protein. choose from among the following: disulfide bond, salt bridge
The ion is stabilized due to the delocalization of the positive charge to the aromatic ring. Draw resonance structures that indicate the stability of this ion.
