The Effect of pH Level on Corrosion Rate of Aluminum and Copper

The effect of weight loss of Aluminium and copper on corrosion rate was studied using two different temperatures (25 and 50)oC and different pH (4.8,7, and 8.2 ).It was shown that the weight loss was decreased with the increasing in pH, this effect on the corrosion rate which decrease with increasing in pH. Temperature effect on weight loss, higher weight loss was observed with the increasing in temperature, higher weight loss in (pH=4.8) in Aluminium & Copper
