What is the molar solubility of Fe OH 3 in water?

What is the solubility of Fe(OH)3 in mol L–1? Ksp (Fe(OH)3) is 2.8 × 10–39 at 25 °C. From the chemical equation, Ksp = [Fe3+(aq)][OH-(aq)]3. Before the Industrial Revolution, the concentration of OH–(aq) in the oceans was about 1.6 × 10–6 M.

What is the molar solubility of Fe OH 2 in water?

The molar solubility of Fe(OH)2 in pure water is 3.489×10-9 M.

What is the solubility of AGCN in a buffer solution of Ph 3?

5. 5×10−3M.

What is the solubility of AGCN in a buffer solution of pH 3?

How do you find the KSP of Fe Oh 2?

Given Question: Calculate the molar solubility of Fe(OH)2 (Ksp=4.87*10^-7).

What is the KSP for feoh2?

4.87 x 10-17
The Ksp of iron(II) hydroxide, Fe(OH)2, is 4.87 x 10-17.

What is the solubility product KSP of AgCN?

Calculate the solubility of AgCN in a buffer solution of pH = 3, Ksp of AgCN = 1.2 × 10^-15 and Ka of HCN = 4.8 × 10^-10 .

What is the solubility of Fe(OH)3?

You need to know the Ksp for Fe (OH)3 to do this. The Ksp is 6 x 10^-38. Bottom line is, Fe (OH)3 is not very soluble. To get what the solubility is, however, you will also need one additional piece of information, the Ka of ammonium ion (=5.6 x 10^-10) ( so that you can calculate the concentration…

How can I calculate the concentration of Fe(3+) in hydroxide solution?

So, if you can determine the concentration of hydroxide, you will be able to calculate the concentration of Fe (3+) and this will correspond to the amount of Fe (OH)3 you can get into solution. The concentration of ammonium ion is 2 M, H3O+ is then 2*Ka=1.12×10^-9 so [HO-] will be 10^-14/1.12*10^-9 = 8.9 x 10^-6.

How do you remove Fe(OH)3 from a solution?

The unreacted Fe (OH)3 can be removed by filtration. The filtrate containing sodium aluminate is neutralised with HCl, and then treated with aqueous ammonia (NH4OH) when Al (OH)3 will be again precipitated. Why is Fe+3 insoluble and Fe+2 soluble?

What is the solubility of iron(III) hydroxide in ammonium buffer?

Iron(III) hydroxide is very insoluble and will precipitate out of solution (there is a whopping excess of ammonium buffer so Fe(NO3)3 will be the limiting material). But from the information given, you can’t calculate the solubility. You need to know the Ksp for Fe(OH)3 to do this.
