Answer:
Concentration of NaOH= 0.0036 M
Explanation:
Given data:
Volume of HCl = 25 mL
Concentration of HCl = 0.05 M
Volume of NaOH = 345 mL
Concentration of NaOH = ?
Solution:
Formula:
C₁V₁ = C₂V₂
C₁ = Concentration of HCl
V₁ = Volume of HCl
C₂ = Concentration of NaOH
V₂ = Volume of NaOH
Now we will put the values in formula.
C₁V₁ = C₂V₂
0.05 M × 25 mL = C₂ × 345 mL
1.25 M.mL = C₂ × 345 mL
C₂ = 1.25 M.mL/345 mL
C₂ = 0.0036 M
