A solution is prepared by mixing 50mL of 0.100 HCL and 10 mL of 0.200M NaCl. What is the molarity of chloride ion in this solution?
I'm a slow learner so.. I need a step by step guide on how to do this please..

Best ResponseYou've already chosen the best response.0yes, isn't it equal to mol/L?

Best ResponseYou've already chosen the best response.1Molarity = moles of solute / volume of the whole solution

Best ResponseYou've already chosen the best response.0ok.. that is what I have to find out for Cl what i did so far is do the chemical equation,which i'm not sure if right,, NaCl + HCl > Na+ + H+ + Cl

Best ResponseYou've already chosen the best response.0volume of the whole solution so should I add the 0.01 and 0.05?

Best ResponseYou've already chosen the best response.1We are asked to find the molarity of Cl^ ions right? For that we need to find the total moles of Cl^1 ions. We get Cl^1 ions from the solutions right? \[NaCl > Na ^{+ } + Cl ^{1}\] \[HCl> H ^{+} + Cl ^{}\] Yeah to find the total volume u have to add up 0.01 and 0.05

Best ResponseYou've already chosen the best response.0yes, right. total volume will be 0.06L..then what?

Best ResponseYou've already chosen the best response.1yeah now we have to find the total moles of Cl^ ions in both the solution

Best ResponseYou've already chosen the best response.0i need to use the value of the given molarities right? so will it be in NaCl: 0.200 x 0.01?

Best ResponseYou've already chosen the best response.1now u have to add up the moles from both solutions and put it on the molarity equation

Best ResponseYou've already chosen the best response.0okay... so total volume: 0.06 #of moles of Cl= (0.200 x 0.01) + (0.05 x 0.100) = 0.007 so 0.06/0.007 which is equal to 0.12 M?

Best ResponseYou've already chosen the best response.1moles divided by the volume not the other way round !!!!

Best ResponseYou've already chosen the best response.0oh yeah, i typed it wrong sorry lol I put 0.007/0.06 on my paper it's right i think :D the book says 0.117

Best ResponseYou've already chosen the best response.1yp yp that's the answer :)
