What are the molar and normal concentrations of a NaOH solutions by dissolving 1

Question

What are the molar and normal concentrations of a NaOH solutions by dissolving 10 grams of sodium hydroxide in 500 ml of pure water? What is the ppm concentration of Na+ if the density of the solution is 1.05 g cm ? (Na = 23, O = 16, H = 1)? Ammonium nitrate can dissociate in water to form nitrate and ammonia ions: A 100-ml dilute solution of ammonium nitrate solution contains 34 mg NH4+ and 124 mg NO3+. What are the ppm concentrations of the two ions? Find the normality of the following solution (C = 12, O = 16, H = 1, P = 31) 45 mg CO3 2/liter, with respect to CO3 2 + 2 H+ H2CO3. 49 mg H3PO4/liter, with respect to H3PO4 + 2 H+ HPO4 2. 49 mg H2PO4/liter, with respect to H3PO4 + 3 H+ PO4 3- What is the pH value of the solution in Problem #1? What is the pH value of a solution containing 0.001 M of formic acid (HCOOH) What would be the pH value if the initial concentration of HCOOH in Problem #5 were 0.005 M (5X increase in concentration)? Comment on your answer. Report qualitatively the following titration curves pH versus ml of titrant, strong acid titrated by strong base. [H+] versus ml of titrant, strong acid titrated by strong base. pH versus ml of titrant, weak base titrated by strong acid. pH versus ml of titrant, weak acid titrated by strong base. (This is a tricky one, think about Calculate the equilibrium pH of a solution containing (a) 10 M HCl; (b) 10 M HCl.
