A new solid Ni(II) octahedral complex has been synthesized containing only chloride and ammonia as ligands. Determine the exact formula of the compound. When 9.64x10-4 moles of this complex is dissolved into 425.0 mL of the water, you find that 19.22 mL of 0.1000 M HCl is needed to reach a titration endpoint. If not enough data is given, show what variables you would need to finish the problem as well. Make sure that your final formula contains the necessary counter ions to make a neutral salt.
A 15.0- mL sample of 0.100 Ba(OH)2 is titrated with 0.125 M HCl. Calculate the pH for at least five different points throughout the titration curve and make a sketch of the curve.
