Final answer:
To neutralize 4L of 2.5M HCl, you would need 10L of 0.5M Ca(OH)2.
Step-by-step explanation:
To determine the amount of 0.5M Ca(OH)2 needed to neutralize 4L of 2.5M HCl, we can use the formula C₂V₁ = C₂Vb. Here, C₂ is the concentration of Ca(OH)2, V₁ is the volume of Ca(OH)2, Cb is the concentration of HCl, and Vb is the volume of HCl.
First, let's substitute the given values into the formula:
C₂V₁ = C₂Vb
0.5M * V₁ = 2.5M * 4L
Now we can solve for V₁:
V₁ = (2.5M * 4L) / 0.5M
V₁ = 10L
Therefore, you would need 10L of 0.5M Ca(OH)2 to neutralize 4L of 2.5M HCl.
