Calcule el valor de [OH−] en una disolución preparada disolviendo 0.0050 mol de amoniaco y 0.0050 mol de piridina en la suficiente cantidad de agua para tener 200 mL de disolución. Los valores de Kb del amoniaco y la piridina son, respectivamente, 1.75 × 10−5 y 1.78 ×10−9. ¿Cuáles son las concentraciones de los iones amonio y piridinio? Resp. [OH−] = [NH4 +] = 6.6 × 10−4; [ion piridinio] = 6.7 × 10−8

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
