If it takes 2.0 L of 5.0 M NaOH to neutralize 5.0 of an HCl solution, what is the concentration of the HCI?
O 20M
-20 M
5.0M
20 M

Answer 1

2 M

Step-by-step explanation:

If it takes 2.0 L of 5.0 M NaOH to neutralize 5.0 of an HCl solution, the concentration of the HCI is 2 M.

2 Liters of 5 molars = 2 x 5 = 10 moles

Answer 2

2 M.

Step-by-step explanation:

I mole of NaCl reacts with 1 mole of HCl ( from the equation).

2 Liters of 5 molar contains 2 * 5 = 10 moles of NaCl so this will neutralise 10 moles of HCl.

So the concentration of 5 liters of HCl must be 10/5 = 2M.
