The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
PH of solution at 25ºC = 8.3
![[ H_3O^+] = 10 ^{-pH}](https://tex.z-dn.net/?f=%5B%20H_3O%5E%2B%5D%20%3D%2010%20%5E%7B-pH%7D%20)
![{H_3O^+] = 10 ^{-8.3}](https://tex.z-dn.net/?f=%7BH_3O%5E%2B%5D%20%3D%2010%20%5E%7B-8.3%7D)
![[H_3O^+] = 5.011*10^{-9} M](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%20%3D%205.011%2A10%5E%7B-9%7D%20%20M)
hope this helps!
Answer:
A) CaF 2 (Calcium Fluoride)
C KBr (Potassium Bromide)
D) Mgl 2 (Magnesium Iodide)
Explanation:
All the above are electrolytes, because of their ability to dissociate/ionize when dissolved. Strong electrolytes completely ionize when dissolved, and not neutral molecules are able to form in the solution. Electrolytes are substances that conduct electric currents as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals (cathode and anode) of an electric circuit, respectively.
