Answer:
Volume required from standard solution = 4675 mL
Explanation:
Given data:
Final volume = 75.0 mL
Final molarity = 130 M
Molarity of standard solution = 2.000 M
Volume required from standard solution = ?
Solution:
We use the formula,
C₁V₁ = C₂V₂
here,
C₁ = Molarity of standard solution
V₁ = Volume required from standard solution
C₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula,
C₁V₁ = C₂V₂
2.000 M × V₁ = 130 M × 75.0 mL
V₁ = 9750 M. mL / 2.000 M
V₁ = 4675 mL
Answer:
The concentration of H3O+= 0.15M
Explanation:
From The equation of reaction
HClO2(aq) + H2O(l) ⇌ H3O+(aq) + ClO2−(aq)
0.25mol HClO2(aq) 0.25mol producesClO2−(aq) and x-mol of H3O+
Using Kc = [H3O+][ClO2-]/[HClO2]
0.15= 0.25*x/0.25
Simplify
x=0.15M
