A 25.00mL soultion of propionic acid, of unknown concentration was titrated with 0.104 M KOH. The equilvalence point was reached when 35.31 mL of base was added. What is the concentration of the original acid?
0.0736M
0.128M
0.162M
0.295M
What salt is most soluble in water?
BaSO4 Ksp= 1.0x10^-10
AgCl Ksp= 1.6x10^-10
BaCO3 Ksp= 9.1x10^-9
PbSO4 Ksp= 1.1x10^-8
What is the best way to be sure that MnS has completely precipitated from a saturated H2S solution?
add a weak acid
add Na2S
add a strong acid
heat the solution
If the Ksp for Pb3(PO4)2 = 10^-44 and two solutions are mixed, 1 containing Pb+2 is 10^-10M and PO4^-3 is 10^-8M, which statement is true?
a precipitate forms b/c Qsp<Ksp
no precipitate forms b/c Qsp=Ksp
no precipitate forms b/c Qsp<Ksp
no precipitate forms b/c Qsp>Ksp
help please!!
