What is the concentration of chloride ion made from an #80mL# volume of #0.125molL^-1# #CaCl_2(aq)# that is diluted to a #100mL# volume?

Answer 1

#[Cl^-]# #=# #("Moles of chloride ion")/("Volume of solution")#

#"Moles of chloride"/"Volume of solution"#

It is observed that every equivalent of calcium chloride present in the solution contributes two equivalent halide ions.

#[Cl^-]##=# #(2xx0.125*mol*cancelL^-1xx80xx10^-3cancelL)/(100xx10^-3L)#

#=# #??mol*L^-1#

The concentration of chloride ion in the diluted solution is 0.1 mol/L.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
