What concentration of 4L NaOH (MM-40) do you need to neutralize 2L of 2M HF?

Given: \[C_1V_1 = C_2V_2\]

A. 4M
B. 0.5M
C. 1M
D. 1.5M
E. 2M

Answer :

Final answer:

To neutralize 2L of 2M HF, a concentration of 1M NaOH is required.


Explanation:

To find the concentration of NaOH needed to neutralize 2L of 2M HF, we can use the formula C₂V₁ = C₂V₂. In this case, C₁ represents the concentration of NaOH, V₁ represents the volume of NaOH, C₂ represents the concentration of HF, and V₂ represents the volume of HF.

First, rearrange the formula to solve for C₁:
C₁ = (C₂V₂) / V₁

Substituting the given values, we have:
C₁ = (2M * 2L) / 4L = 1M

Therefore, the concentration of 4L NaOH needed to neutralize 2L of 2M HF is 1M.
