Problem 2: What is the equilibrium concentration of bromide ion when enough PbBr2 dissociates in water to make a saturated solution? Ksp (PbBr2) = 2.1 × 10-6. Solution: In the equation for the dissociation of CaCO3, we see that the concentration of Ca+2 and CO32- must be the same...
The concentration of Pb2+ (aq) in the saturated solution is found to be 1.3 × 10 − 3 M . The chemical equation for the dissolution of PbI2(s) in water is shown below. PbI → 2+ − 2(s) ← Pb (aq) + 2 I (aq) (i) Write the equilibrium-constant expression for the ...

In 1909, Danish biochemist Søren Peter Lauritz Sørense proposed the following equation forcalculating pH: pH = -log[H+] where log is the base-10 logarithm and [H+] stands for the hydrogen ion concentration in units of moles per liter solution. The term "pH" comes from the German ...
