Assuming the volumes are additive, what is the nitrate ion concentration in a solution made by mixing 267.0 mL of 1.022M magnesium nitrate aqueous solution, 433.5 mL of 0.778M Ni(II)nitrate aqueous solution, and 125.0 mL of distilled water

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

Evaluate this exponential expression,8. (2 + 3)2 – 42
