Answer:
Racemic mixture of racemate
Explanation:
A racemic mixture or racemate is a mixture with the same amount of left- handed and the right handed enantiomers.
The main characteristic of a racemic mixture is that is optically inactive, that means that can not rotate polarized light. Also a racemic mixture has other different physical properties than the pure enantiomers.

- High Tide - when tides are at their highest elevation
- Low Tide - when tides are at their lowest elevation
- Spring Tide - when tides experience the greatest range between high and low; occur at New and Full Moons
- Neap Tide - when tides experience the least range between high and low; occur at 1st and 3rd Quarter Moons
- Gravitational Pull - the invisible force that exists between all objects that have mass. The greater the mass, the greater the effect of the force
- Tide - the daily change in ocean levels due to the gravitational force of the moon and the sun exerted on Earth

The three situations can be described as
a) If we have two white powders and wish to distinguish between the two : the combinations can be sugar / salt or sugar / baking soda or salt / baking soda
all are kitchen items so we can either taste them
or in case of baking soda we can add it in water and it will produce brisk effervescence.
b) IF we have to distinguish in a given set of two transparent liquids which appear to be water (example water and vinegar)
we can identify them with the taste
we can identify them based on pH (vinegar will be acidic)
c) We have to find adulteration in a given sample of food
like adulteration in milk
for example presence of soap in milk
We can add indicator like phenolphthalein which will bring a pink colour in milk if soap is present
