Explanation:
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.
<h3>What is malic acid?</h3>Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is . Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
<h3>The stereoisomeric forms of malic acid.</h3>
In Science, there are two (2) stereoisomeric forms of malic acid and these include:
- L-enantiomers
- D-enantiomers

Explanation:
Equation for the given reaction is as follows.
Therefore, moles of NaOH and HA are calculated as follows.
Moles of NaOH =
=
= 0.00864 mol
Moles of HA = 0.00864
Also, moles =
Molecular weight =
= 122.22 g/mol
Thus, we can conclude that molar mass of given unknown organic acid is 122.22 g/mol.
