25 mL of 0.100 M AgNO3 are mixed with 35 mL of 0.0500 M K2CrO4.
(a) Calculate the concentrations of each species at equilibrium.
(b) Is the precipitation of silver quantitative (>99.9%)?
The ksp of Ag2CrO4 is 1.12*10^-12
What is the molecular formula?
water and titrated with 0.0633 M NaOH. After 10.0 mL of base has been added, the pH was determined to be 5.07. What is the Ka for the acid?
aqueous solution of sucrose, C12H22O11(aq), which is used frequently in biological experiments. What is the value of x?
Assuming that the appropriate volumetric flasks are available, describe how we would make these solutions: (a)175 mL of a 1.14 M solution of NH4Br in water (b)1.35 L of a 0.825 M solution of NaI in water
