Calculate the volume of 0.25 M sodium chloride solution, in ml, that must be diluted to prepare 50.00 mL of a 0.025 M NaCl solution. Show your work.
Calculate the concentration (M) of sodium ions in a solution made by diluting 30.0 mL of a 0.574 M solution of sodium sulfide to a total volume of 150 mL.
A 0.500 g sample of AgCl was mixed with 250 mL sodium chloride solution of unknown molarity. In order to find the molarity of sodium chloride the amount of dissolved silver ion was monitored with an ion selective electrode at 25 C. The electrode registered the concentration of Ag+ ion to be 3.75x10^-8 M. Calculate the concentration of molarity of the NaCl.
Calculate the hydronium ion concentration and the pH when 30.0 mL of 0.65 M NH3 is mixed with 30.0 mL of 0.65 M HCI ( Ka = 5.6 x 10-10). Concentration = pH =
