Below is the result of a student's efforts to determine the solubility product, Ksp, of strontium chromate. The concentration of Sr2+ in the reference cell is 0.00100 M. The concentration of chromate in the nonreference cell was calculated to be 0.993 M. The voltage of this nonreference cell relative to the reference was measured as -49.0 mv. The temperature is 25.0 C NOTE The voltage is recorded as negative due to the way the silver electrodes are placed in the...
