Methyl orange and screened methyl orange are both synthetic dyes commonly used as indicators in titrations. They both change color at specific pH ranges: methyl orange transitions from red to yellow in acidic solutions, while screened methyl orange transitions from yellow to red in basic solutions. Both dyes are water-soluble and widely available for laboratory use.
It is a mixture!
Menthol sublimates quite easily.If you can get your hand on a bottle of pure menthol you can observe very fine crystalline needles of menthol - not only on the bottles ground but also from the sides or the top. They grow by resublimation. This means that solid menthol sublimates (s --> g) and the vapour resublimates on surfaces (g-->s).
A pure substance is a sample of matter with both definite and constant composition with distinct chemical properties. Examples: water, diamond, gold, table salt (sodium chloride), ethanol Salt water is not a pure substance because it is a mixture of two compounds, NaCl and H2O. Orange juice again is a mixture of sugar, water and orange pulp. So it is not a pure substance. Duct tape is made of three layers: Layer 1: A Resilient Plastic Layer 2: A Fabric Mesh Layer 3: Rubber Based Adhesive So it is certainly not a pure substance. Baking soda, on the other hand, is a pure substance because it is a compound (NaHCO3) and all compounds and elements are considered pure substances.

no Its a solution. If you mix salt in water, the salt dissolves. It is then a solution. That is not a mixture. It may well be a pure substance. If it is pure salt water it is pure. But if you add some soap it is then pure soapy salt water. What does pure mean? Pure is not a scientific term, so its meaning is debatable. Pure orange juice for instance, has no real meaning as orange juice contains many different things, so how is it pure? In fact if by the previous persons definition of pure, [wood is not but glass is] is incorrect as glass is a compound of several things as is wood. Pure water is a compound of hydrogen and oxygen. So is that pure ,or not?
