Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
Can you explain this problem in detail? And where does the 2+ From Ca came from and how do you find it.
![Will a precipitate form when 50.0 mL of 2.0 x 10-2 M NaF is mixed with 10.0 mL of
1.0 × 10 2 M Ca(NO3)2? Ksp = 3.9 ×10-11
Solution
We must get the Molarities of the principal ions that will lead to the precipitation.
Neither Na+ nor NO3 will precipitate, so we're left with Ca2+ and F as the ions that will form
the precipitate.
moles Ca2+ = 0.010 L x 0.010 M = 1.0 × 10-4 moles Ca2+
moles F= 0.050 L x 0.020 M = 1.0 x 10-3 moles F-
total volume = 50.0 mL + 10.0 mL = 60.0 mL
1.0 × 10-4 mol
[Ca2+] =
1.0 x 10-3 mol
= 1.67 x 103 M
[F] =
= 1.67 x 10-2
0.060 L
0.060 L
CaF2 (s) -
Ca2+ (aq)
+
2F- (aq)
4.6 x 10-7
Qsp = [Ca2+] [F]² = (1.67 x 10-3) (1.67 x 10-2)²
Thus: Qsp > Ksp, and a precipitate WILL form!!](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F637a8243-98d2-45ca-8dd1-4e9d7d0f97ca%2Fd5c73eb3-8483-473e-ad06-2561b886373c%2Fn2glzdi.jpeg&w=3840&q=75)
