Calculate the concentration of iodate ions in a saturated solution of lead(II) iodate if Ksp = 2.6 × 10-13.
Consider the 1H19F molecule. The bond length of 1H19F is 91.7 pm. The wavenumber of light associated with a transition from the ground vibrational state to the first excited state is 1159.18 cm^-1.
The thermocouple is then placed in boiling toluene at the same pressure and provides an output of 12.59 mA.
What is the molar solubility of lead chromate in 0.10 M HNO3 if the Ksp for PbCrO4 is 2.8 x 10^-13 and Ka2 for H2CrO4 is 3.0 x 10^-7. Note that H2CrO4 is considered to be a strong acid.
