How do you write a KSP expression?
How do you write a KSP expression?
Ksp=[M+][X−][MX(s)] , but MX(s) as A SOLID cannot express a concentration, and thus the expression simplifies to… Usually standard conditions are specified, because a hot solution can generally hold more solute than a cold one. have been measured for a host of insoluble, and semi-soluble ionic salts.
What is the correct expression for the representation of the solubility product constant of Ag2CrO4?
Ksp=[Ag+]2[CrO42−]
Why is there no KSP value for NaCl?
Originally Answered: why solubility product concept is not applicable to soluble salts like NaCl? Nacl being very strong electrolyte has dissotiation constant ksp very very large.so it almost completly breaks into na+ and cl-. It means reaction go completly forward . so there is no need to consider ksp.
Does higher KSP mean more soluble?
The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.
What does a lower KSP mean?
Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a solution. The value of the constant identifies the degree of which the compound can dissociate in water. For example the higher the Ksp the more soluble the compound is.
Why is precipitate formed?
Precipitates are insoluble ionic solid products of a reaction, formed when certain cations and anions combine in an aqueous solution. The solids produced in precipitate reactions are crystalline solids, and can be suspended throughout the liquid or fall to the bottom of the solution.
Which will precipitate first when AgNO3?
AgI will precipitate first when AgNO3 is added to a solution containing equal concentrations of Br− , Cl− , and…

Is least soluble in water?
Solution : Due to lack of hydrogen bonding, alkane is least soluble inter. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Which is more soluble BeF2 or BaF2?
BaF2 being more ionic in nature, will be more solube in polar solvents like water. For more information kindly go through Fajan’s rule in Chemical bonding.
Which is more soluble nahco3 or khco3?
Higher the lattice energy, difficult to break the lattice and hence the solubility is lesser. The actual reason for having higher solubility of potassium bicarbonate over sodium bicarbonate is due to decrease in lattice energy more rapidly over then their hydration energy down the group.
Which of the following is least soluble in water baf2?
BeF2>MeF2>CaF2>SrF2 so SrF2 is least soluble.
Which will have higher melting point BeF2 or MgF2?
A SrF2 CORRECT ANSWER B BeF2 BaF YOUR ANSWER D MgF2 SOLUTION The melting point of a compound depends on Vander walls force of attraction which increases as molecular size increases, in given compounds Sr atom has the largest size, so vanderwalls force of attraction will be greater in SrF2 and it will have the highest …
Which substance has highest melting?
tungsten
Does MgO or al2o3 have a higher melting point?
The reason as to why Al203 has lower melting point than MgO is because of the fact that Mg has more ionic character compared to Al. Generally it is found that more ionic the material is, the higher is the melting point. A corollary to this is that the more covalent a compound is the lower will be the melting point.
Does magnesium oxide have a high melting point?
2,852 °C
