The equation of the line for a graph of voltage versus log[Cu2+] was y= - 0.0179x - 0.0015. The voltage of a solution with an unknown [Cu2+] was measured against the same reference cell, under the same conditions; the voltage was found to be 0.012 V. Determine the [ Cu2+] of the unknown solution.

  1. y = 0.012 V = - 0.0179x - 0.0015
    x = log[Cu2+]
    10^x = [Cu2+]
