Solution of HCl Concentration Calculation
Given:
- Volume of 0.2M HCl = 1L
- Volume of xM HCl = 500mL = 0.5L
- Concentration of resulting HCl solution = 0.25M
Calculation
Let's assume the concentration of the xM HCl solution is x M.
The amount of HCl in 1L of 0.2M HCl solution is:
0.2M x 1L = 0.2 moles
The amount of HCl in 0.5L of xM HCl solution is:
xM x 0.5L = 0.5x moles
The total amount of HCl in the resulting solution is:
0.2 + 0.5x moles
The total volume of resulting solution is:
1L + 0.5L = 1.5L
Using the formula:
M1V1 + M2V2 = M3V3
Where:
- M1 = 0.2M
- V1 = 1L
- M2 = xM
- V2 = 0.5L
- M3 = 0.25M
- V3 = 1.5L
Substituting the values:
(0.2M x 1L) + (xM x 0.5L) = (0.25M x 1.5L)
0.2 + 0.5x = 0.375
0.5x = 0.375 - 0.2
0.5x = 0.175
x = 0.35M
Answer
The value of x is 0.35M (Option b).
