Racemic mixtures and meso compounds?
A racemic mixture contains equal amounts of two enantiomers, resulting in no overall optical activity. In contrast, a meso compound is a molecule with chiral centers but possesses an internal plane of symmetry, making it optically inactive despite having stereogenic centers.
Would you expect a solution of a meso compound to rotate plane polarized light?
No, meso compounds do not rotate plane-polarized light because they have an internal plane of symmetry. This means that any rotation induced by one half of the molecule is cancelled out by the opposite rotation of the other half.
Strength measurement of sugar solution using polarized light?
The strength of a sugar solution can be determined by measuring the rotation of polarized light passing through the solution using a polarimeter. Sugar molecules rotate the plane of polarized light, and the degree of rotation is proportional to the concentration of sugar in the solution. By measuring this rotation angle, the strength or concentration of the sugar solution can be calculated.
What is the color of a solution containing a compound that absorbs most strongly at 460 nm?
The solution would appear blue. Absorption of light at 460 nm corresponds to the complementary color on the visible spectrum, which is blue.
How is solute a solution not a compound?
Solute is a compound dissolved in a solution.
What is the pH of a solution containing the compound NaH2PO4?
The pH of a solution containing NaH2PO4 is around 4.5.

What is the molar mass of a solution containing 2000 grams?
Only a compound has a molar mass not a solution.
Are there elements in solutions?
There can be elements or compounds in solution. For instance, sodium chloride is a solution of a compound. Conversely, a solution of bromine is a solution containing an element.
Name one compound containing large anions which can be used for precipitation of potassium ions from aqueous solution?
Sodium tetraphenylborate (NaB(C6H5)4) is a compound containing large anions that can be used to precipitate potassium ions from aqueous solution. When added to a solution containing potassium ions, insoluble potassium tetraphenylborate precipitates out.

No, meso compounds do not rotate plane-polarized light because they have an internal plane of symmetry. This means that any rotation induced by one half of the molecule is cancelled out by the opposite rotation of the other half.

What does base?
A base is generally a compound containing the anion -OH an forming a solution with a pH greater than 7,00.
How do you know which compound it is by adding silver nitrate?
For example, adding silver nitrate solution to a solution containing halogen ions: formation of a white insoluble precipitate.
What metal reacts spontaneously with a solution containing zinc ions?
Aluminum is a metal that reacts spontaneously with a solution containing zinc ions, displacing the zinc from the solution due to aluminum's higher reactivity. This reaction is known as a displacement reaction where aluminum replaces zinc in the compound.
How sucrose rotate polarized light?
Sucrose, a type of sugar, is a chiral compound, meaning it has a specific spatial arrangement of atoms that allows it to rotate the plane of polarized light. When polarized light passes through a solution of sucrose, the light is rotated to the right, a phenomenon known as right-handed or dextrorotatory rotation. The degree of rotation depends on the concentration of the sucrose solution and the wavelength of the light used. This optical activity is a characteristic property of many chiral substances.
What is seawater element compound heterogeneous or homogeneous?
Seawater is water (H2O which is a compound) containing soluble compounds but also insoluble materials. We can consider, with approximation, that the seawater is a homogeneous solution.
