- Write equations for the stepwise formation of each of the following complex ions. a. CoF63 b. Zn(NH3)42+arrow_forward理 E The equilibrium concentration of hydroxide ion in a saturated cobalt(II) hydroxide solution isarrow_forwardGiven the equation: Ag+(aq)+2NH3(aq)⟶[Ag(NH3)2]+(aq) ?f=2.00×10^7 determine the concentration of NH3(aq) that is required to dissolve 295 mg of AgCl(s) in 100.0 mL of solution. The ?sp of AgCl is 1.77×10^−10. I've worked this through several times, but I am just not coming up with the right answer! Thanks :)arrow_forward
- Potassium hydrogen phthalate (KHP) concentrations can be determined through titrating samples of KHP (a monoprotic acid) with bases such as NaOH in the presence of an indicator such as phenolphthalein. The indicator is colorless in an acidic solution and turns pink in an alkaline solution. Thus, we can establish an equilibrium for the phenolphthalein with the following reaction. HIn + H2O ⇌ In− + H3O+ If the HIn species is "acid color" or colorless for the phenolphthalein, and the In− species is "base color" or pink for this particular indicator, what color will appear in a flask in which a 0.2993 gram sample of KHP is completely neutralized with an excess of NaOH? The flask will be colorless. The flask will be pink. The flask will be white from KCl precipitation.
