Nov 05, 2013 · This gives Q = 0.92 for this point. Since this exceeds Q c for five data points (for N = 5, Q c = 0.64 in Table 2), this point may be excluded on the basis of the Q-test. The Q-test may not be repeated on the remaining data to exclude more points. One last important thing about the Q-test is that it cannot be performed on identical data points

halogens in aqueous solution and their displacement

halogens in aqueous solution and their displacement

Halogens react to a small extent with water, forming acidic solutions with bleaching properties. They also undergo redox reactions with metal halides in solution, displacing less reactive halogens from their compounds. These displacement reactions are used to establish an order of reactivity down Group 17 of the periodic table
