Use the equation displayed on the graph to answer a and b A metal(II) ion solution of an unknown concentration shows an a. absorbance of 0.6. What is the approximate molar concentration of the metal(II) ion? For a metal(II) ion solution having a 0.00014 M concentration, what would be the predicted absorbance?
Question A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...

9. What is the hydroxide-ion concentration in a solution formed by combining 200 mL of 0.16 M HCl with 300. mL of 0.091 M NaOH at 25°C? HCl(aq) + NaOH(aq) + NaCl(aq) + H2O(1) 10. What is the pH of a solution prepared by dissolving 0.241 L of HCl(g), measured at STP, in enough water such that the total volume of the solution is 2.00 L? (R = 0.0821 L.atm/(K.mol)) (Use gas law equation to calculate Mole of HCl dissolved...
