Why is it necessary to scratch the sides of the beaker for crystals to form?

Because i think that this will help form the crystal by getting things off the sides and help the crystal disolve. If not i don't think it is necessary.

What do you observe on the sides of the beaker?
Some beakers have graduations and a label.
Why do the sides go up on the beaker in meniscus?
Assuming that the liquid in the beaker is water.... Due to the structure of water (two hydrogen, one oxygen), it has a slight negative charge near the oxygen atom an a slightly positive charge near the hydrogen atoms. These slight charges allow the edges of the water to cling to the sides of the beaker, thus creating a meniscus. Some liquids, like mercury, actually would create a reversed meniscus (compare an alcohol thermometer with a mercury one).
What is a laboratory beaker?
A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generally cylindrical in shape, with a flat bottom. A beaker is like a glass jar, but it has very straight sides, a flat base and a slightly wider top with a spout/lip for pouring. The sides are often marked/graduated to indicate volume/capacity measures. It is used in laboratories for holding or measuring liquids for experiments.See Related Link below ads
How many sides does the hexagonal crystal have?
It depends on the gem all gems are diffrent18 i thinkAmethyst is the violet variety of quartz; its chemical formula is SiO2.The crystaline form is rhombohedralThe rhombohedral system can be thought of as the cubic system stretched along a body diagonal. a = b = c; α = β = γ ≠90°.There are six sides to a pure simple crystal.
How can you distinguish a sill from a buried lava flow?
These extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain
What is the difference between a beaker and a flask?
The shape of the opening. A Beaker has a wide opening, the curved sides of the beaker do not converge. A flask has a narrow opening, the curved sides form a narrow neck, that can be bunged.
What does the dashed line in the beaker separating the two sides of the beaker represent?
I don´t know jajajajajajaj
Why is it important to have the bulb of a thermometer submerged in liquid without touching the sides or bottom of the beaker?
The sides or bottom of the beaker will likely be at a significantly different temperature than the liquid.
Why is it not allowed to let the bulb of the temperature touch the bottom nor sides of the beaker that contains your liquid measuring the temperature?
The bottom and sides of the beaker will be hotter than the liquid inside.
Does all crystals have eight square sides?
Some crystals have 6 sides while others have 4. Some of the four sided are rhombuses
What do you observe on the sides of the beaker?
Some beakers have graduations and a label.
Does quartz always have six sides?
No. Quartz will only have six sides if it has space to grow unrestricted and if the crystals are not broken or weathered.
Does a quartz crystal always have 6 sides?
Most Quartz crystals have 6 sides, But some of them have more or less. Hope that helped:)
Why shouldn't the thermometer touch the walls of the distillation head?
because the sides of the beaker will be slightly at high temperature
How do you count the sides of a square?
It's not necessary to count. Squares always have four sides.
Does a beaker measure liquids?
Calibrated beakers have markings on their sides used for measurement. The accuracy of the reading depends upon the observer.
How many faces does a hexagonal crystal have?
If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
