When the compound PbI₂ dissolves, it dissociates as follows;
PbI₂ --> Pb²⁺ + 2I⁻
Molar solubility is the number of moles dissolved in 1 L of solution
A saturated solution is when the maximum amount of solute is dissolved in the solution.
Molar solubility of Iodide when solution is saturated is 2.7 x 10⁻³ mol/L, then solubility of Pb²⁺ is (2.7 x 10⁻³ mol/L) / 2 = 1.35 x 10⁻³ mol/L
ksp is the solubility product constant that can be calculated as follows;
ksp = [Pb²⁺][I⁻]
ksp = (1.35 x 10⁻³ mol/L) x (2.7 x 10⁻³ mol/L)²
= 1.35 x 10⁻³ x 7.29 x 10⁻⁶
= 9.8 x 10⁻⁹
Answer:
M=0.380 M.
Explanation:
Hello there!
In this case, given those two solutions of aluminum bromide and zinc bromide, it is firstly necessary to compute the moles of bromide ions in each solution as shown below:
Now, we compute the total moles of bromide:
Then, the total volume in liters:
Therefore, the concentration of total bromide is:
Best regards!
Answer:
a) should be an answer that is like "matches" or "equals" or "is equal to"
b) should be "conservation of mass"
c) can't be sure because I'd need to see the answer choices, but it should be a properly balanced chemical equation (one with the same number and type of atoms on both sides)
Explanation:
Different wavelength are involved.
Explanation:
If magnesium burns with a bright white flame, one can conclude that different wavelengths accompany the electron transitions for the magnesium atom.
- When an atom burns, the electrons in it are excited.
- They give out characteristic light commensurate with their energy.
- A white light is made up of different combinations of wavelength of radiations.
- When we see a white light we can infer that different joined together in the emission observed.
