4.56 A metallurgical firm needs to dispose of 2.74 x 10 3 gallons of waste sulfuric ,acid, whose Concentration has been determined to be 1.53 M. Environmental regulations require them to neutralize the waste before releasing the ,wastewater,, and they choose to do so with slaked lime, Ca(OH) 2 (s). The ,neutralization, reaction is H 2 SO 4 ( aq ) + Ca ( OH ) 2 ( s ) → CaSO 4 ( s ) + 2 H 2 O ( l )
