Solid cobalt(II) hydroxide dissociates in water according to the following expression. Co(OH)2(s) Co2+(aq) + 2 OH-(aq) If 1.00 L of saturated Co(OH)2 solution is neutralized by 15.20 mL of 0.00150 M HCl, what is the Ksp of Co(OH)2? 1000 mL = 1 L. (Hint: Co(OH)2 is quite "insoluble" in water.)
The molarity (moles/L = M) of a solution of 4.0 g NaOH in a total volume of 100.0 mL (or 40 g in 1.0 L) is what?
when the following five solutions are mixed together, only one reaction occurs. write the net ionic equation for that precipitation reaction. KCl(aq),Cu(NO3)(aq),AgNO3(aq),CaCl2(aq),and Ba(No3)2(aq)
