A mmonia is highly soluble gas in water and gives a alkaline solution of NH_(4) OH . What volume of NH_(3) gas at STP will be required to the passed in 100 mL of 0.5 M H_(2) SO_(4) to bring down its strength to 0.25 M ? (For titrations with aqueous NH_(3) , it is assumed that NH_(4) OH dissociates to 100% extent) a. 2.24 L b. 1.68 L c. 1.12 L d. 0.56 L
