Question

Calculate titration using the equation (Macia) (Vacid) = (Mbase)(Vbase)

It takes 20mL of 0.5M NaOH to titrate 35mL of HCI. What is the concentration of HCI?

Answer 1

To find the concentration of HCl, we can rearrange the given equation (Macia)(Vacid) = (Mbase)(Vbase). By plugging in the given values and simplifying the equation, we find that the concentration of HCl is 0.286 M.

Step-by-step explanation:

To find the concentration of HCl, we can use the equation:

(Macia)(Vacid) = (Mbase)(Vbase)

In this case, we can rearrange the equation to solve for the concentration of HCl:

(Mbase)(Vbase) = (Macia)(Vacid)

Plugging in the given values, we have:

(0.5 M)(20 mL) = (Mbase)(35 mL)

Simplifying the equation, we find that the concentration of HCl is:

Mbase = (0.5 M)(20 mL) / (35 mL) = 0.286 M
