Determine the degree of ionization of this acid. asked Mar 16, 2019 in Chemistry by Rabia (87.3k points) acids; bases; jee; jee mains; Pyridine reacts with water according to the following equation: C5H5N + H2O ---> C5H5NH+ + OH-. 0.100 M HCl and 0.100 M NaOH ___C6H6 basic, 2.41 10^-9 M H2O = 4, Cl- = 6 4.65 10-3 M This has been going on for about a week Every time I try to watch a video on Youtube from my laptop I get instantly redirected to "gslbeacon.ligit.com." Ksp for Fe(OH)2= 4.87 10-17. K = [P]^1/2[Cl2]^1/3/[PCl3]^1/2 6.434, What is the pH of a 2.4 M pyridine solution that has Kb = 1.9 10-9? Mg the F- will grab an H+ from C5H5NH+ making the weak acid HF and C5H5N, Kb C5H5N = 1.710^-9 so, Ka C5H5N = 5.8810^-6, Your email address will not be published. 512 pm, How many O2 ions are around each Mg2+ ion in MgO, which has a cubic unit cell with O2 ions on each corner and each face? H2O = 7, Cl- = 3 HA (aq) + H_2O (l) to H_3O^+ (aq) + A^- (aq) If the starting concentration of HA a 1.00 times 10^{-3} M solution has a pH = 6.53, determine the K_a for the acid. Mi hermana se sorprende N-F C-F Cl-F F-F 2 Answers C-F is the most polar. Vinegar is a 5.0% solution by weight of acetic acid (CH3CO2H) in water. 6.59 10.2 Chemical stability The product is chemically stable under standard ambient conditions (room temperature) . What is the strongest monoprotic acid of the following set if all the acids are at 0.100 M concentration? A solution contains 0.036 M Cu2+ and 0.044 M Fe2+. Justify your answer.
