An iron tank contains helium at a pressure of 2.5 atm at 250C .The tank can withstand a maximum pressure of 10 atm
P1 = 2.5 atm P2 = ? T1= 25o C =298 K T2 = 15350 C =1808 K According to Gay Laussac law, P1/ T1 = P2 / T2 P2 = 2.5 x 1080/ 298 =15.16 atm. Since...

Why is acetic acid & not nitric acid is used to acidify soda extract for testing of sulphur by lead acetate test?
Lead acetate on reacting with sulphuric acid will give a white ppt of lead sulphate which interferes in the detection of sulphur. (CH3COO )2Pb + H2SO4 ----------> PbSO4 + 2CH3COOH
