What is the ionization constant at 25∘C for the weak acid CH3​NH3​+, the conjugate acid of the weak base CH3​NH2​, Kb​=4.4×10−4. 4 points Calculate the percent ionization of a 0.293 M solution of nitrous acid (a weak acid), with a pH of 1.88. Record to the hundredth's place. Typeyour answer- 4 points Caifeine, C8​H10​ N4​O2​(aq) is a weak base. What is the value of Kb​ for caffeine if a solution at equilibrium has [C8​H10​ N4​O2​]=0.050M [CaH10​ N4​O2​H+]=5.0×10−3M and [OH−]=2.5×10−3M ? Write the ionization of caffeine with water and write the Kb expression. Then solve for the Kb.
