Which reaction occurs at the cathode of a galvanic cell that has an aluminum electron in an electrolyte with aluminum ions in copper electrode in electrolyte with copper ions? The reduction potential for the reduction of Cu^2+ =0.34 V. The reduction potential for the reduction of Al^3+ = -1.68. A. Cu^2+(aq) + 2e- -> Cu(s)
B. Cu(s) -> Cu^2+(aq) + 2e-
C. Al^3+(aq) + 3e- -> Al(s)
D. Al(s) -> Al^3+(aq) + 3e-

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m
