Answer:
B. Add more water to decrease the concentration.
Explanation:
If we add more water to the solution, the concentration is decreased and like wise the conductivity of the solution.
- Concentration is the amount of solute in a solution.
- Conductivity deals with the ability of a solution to allow the passage of current.
Concentration and conductivity are directly proportional to one another. The higher the concentration, the higher the conductivity and vice versa.
- Adding more water increases the amount of solvent and the concentration reduces.
The result of multiplying that equation is 70,700.
Answer:
Explanation:
H2CO3 = H+ + HCO3- H2CO3 = 0.530 M Ka =4.4 X10^-7
Ka =[H+][A-]/[HA] [H+] = [A-]
0.530 M x 4.4 X10^-7= [H+}^2
2.32 X10^-7 = [H+}^2
23.2 X10^-8 = [H+}^2
4.83 X 10^-4 = [H+]
pH = - log 4.83 X 10^-4
pH = -(.68-4)
pH =-(-3.32)
pH= 3.32
