In a saturated solution of an ionic compound in water, there is an equilibrium between the solid compound and the dissolved ions. The equilibrium expression for this type of reaction is called the solubility product constant, Ksp, which can be calculated from the concentrations, in moles per liter, of each ion in solution.

For example, the solubility reaction and solubility product of barium carbonate, BaCO3, are

BaCO3(s)⇌Ba2+(aq)+CO32−(aq)Ksp=[Ba2+][CO32−]

Similarly, the solubility reaction and solubility product of calcium sulfate, CaSO4, are

CaSO4(s)⇌Ca2+(aq)+SO42−(aq)Ksp=[Ca2+][SO42−]

The solubility of barium carbonate, BaCO3, is 0.0100 g/L. Its molar mass is 197.3 g/mol. What is the Ksp of barium carbonate?​

The solubility product constant of calcium sulfate, CaSO4, is 7.10×10−5. Its molar mass is 136.1 g/mol. How many grams of calcium sulfate can dissolve in 57.0 L of pure water?​

The solubility product constant of calcium sulfate, CaSO4, is 7.10×10−5. Its molar mass is 136.1 g/mol. How many grams of calcium sulfate can dissolve in 64.5 L of pure water?

The ksp of CaSO4 is 4.9 x 10^-5 at 25 degrees C. What mass of CaSO4(molar mass 136.1 g/mol) will dissolve in 1.0 L of water at 25degrees C?
answer = 0.95 g

I’m looking at commissioning an artist to make a better ref of my fursona, does anyone know a good artist with a decent price?

Molar mass of CaSO4

Mass of KHP used forstandardization(g) 0.5548
Volume of NaOH required to neutralize KHP(mL) 13.40
Volume of vinegar sample titrated (mL) 5.00
Volume of NaOH required to neutralize vinegarin(mL) 8.53
Molecular weight of ascorbic acid(g/mol) 176.1271
Volume of NaOH required to neutralize ascorbic acid in VitaminCtablet (mL) 13.97

A scientist conducted the volumetric analysis using both Parts A and B and obtained the following data: 0.4985g KHP (molar mass of 204.23 g/mol ) was titrated to endpoint with 15.05mL of NaOH as in Part A. Then as in Part B, 25.0mL of unknown concentration of HCl was titrated to the endpoint with 21.50mL of NaOH. What is the concentration of HCl?

Mass of KHP: __________ Moles of KHP: __________ Moles of NaOH at equivalence point: __________ Volume of NaOH used to neutralize KHP: __________ Molarity of NaOH in the buret: __________
Volume of NaOH used to neutralize HCl: __________ Moles of NaOH used to neutralize HCl: __________ Moles of HCl: __________ Volume of HCl used for titration: __________ Molarity of HCl: __________

20.0mL of 0.16 NaOH is used neutralize 25.0mL of an unknown concentration of HCl in a titration. what is the molar concentration of the HCI

Hello. I need help with the following problem. This problem issimilar to Chapter 17, Problem 39 of book "Fundamentals of Physics"8th edition, ISBN 978-0-470-04473-5. Thank you very much for yourhelp.

Hello. I need help with the following problem. This problem issimilar to Chapter 15, Problem 15 of book "Fundamentals of Physics"8th edition, ISBN 978-0-470-04473-5. Thank you very much.

In the Fundamentals of Physics Extended (8th) book, I don't understand the solution to the problem 71 in chapter 4. Can you explain why it's Vm-Vs for the second part?

What makes physics so cool ? To me, physics is awesome and interesting because it asks the one question no other [ physical ] science does : “How ? ” Physics looks at how things happen-the reason things happen and explains it. The ultimate goal of physics is to understand the universe around us. This ranges from tiny inter-molecular particles to huge things like entire solar systems. Physics has a bad reputation as being one of the hardest sciences you can take in high school. This can be true, but I believe every concept can be broken down and simplified. From the fundamental Newtonian equations to the famous e=mc^2 , together we will embark on a journey to better understand the world around us.
