Question

If 5.0 milliliters of a 0.20 M HCl solution isrequired to neutralize exactly 10. milliliters ofNaOH, what is the concentration of the base?(1) 0.10 M(3) 0.30 M(2) 0.20 M(4) 0.40 M

Answer 1

andand Answer explanationllllll

IfIf wewe hav

n:

We are given: 5ml of HCI solution (volume)

: 0.20 M of HCI solution (concentration)

: 10ml of NAOH solution (volume)

We are required to find: The concentration of NAOH solution

The number of moles of HCI solution is equal to the number of moles of the NAOH solution. Therefore to find the number of moles of HCI solution, we use the following formula:

n = CV

Where: C is concentrationAnswer e
