Find the concentration (molarity) of an aqueous solution prepared by dissolving 10g of NaOH(s) in 100mL of water.
Find the concentration (molarity) of a NaOH solution that contains 5g of NaOH and 1000 mL of water.
What is the new concentration when we add 1L more of water to the prepared solution in question (2).?
If you have 10 ml of a 5M solution of NaOH, how many mol of NaOH you have?
How many mol of Na+ you have?
How many mol of OH- you have?
If you have a 100 ml of a 5 M aqueous solution of NaOH, how much water do you need to add in order to have a 0.1 M solution of NaOH?
NaOH behaves as a strong base when it is dissolved in water. Write the appropriate equation showing this behavior.
