Question

100 mL of a 0.10 mol L^-1 solution of sodium hydroxide (NaOH) is diluted to 1.0 L with distilled water. What is the pH of the diluted solution?

Answer 1

The moles of NaOH in the diluted solution remains the same = n=M.V=0.1*0.1 M
The Volumes changes , which is 1+0.1= 1.1 l.
Get the final molarity , taking its negative logaithm will give you the pOH .
Assuming at 298 K , hence , 14-pOH=pH.

Hope , this helps !

Answer 2

^correct, the final V is 1 L though

Answer 3

Oops , yes ..thanks :)

Answer 4

thank youu! :))
