Paper chromatography can be applied to ink to determine if it is a pure substance or a mixture of pure substances (in which two or more pure substances are combined). Since, when tested with paper chromatography, ink separates into its constituent pure substances, ink is a mixture.

A pure substance will only produce one spot on the chromatogram during paper chromatography. Two substances will be the same if they produce the same colour of spot, and their spots travel the same distance up the paper. In the example below, red, blue and yellow are three pure substances.

The brown ink was also a mixture because it separated into several different colors during the experiment. Some blue inks did separate indicating that they were mixtures but some blue inks did not.

A glass of iced tea is a heterogeneous mixture. The ice cubes have different composition and properties than the tea. You can say that the ice cubes are a solid phase, and the tea is a liquid phase.

Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.

Peanut butter is a homogenous mixture and consists of roasted peanuts (85% minimum), vegetable oil (antioxidant (320), sugar and salt.

Now, since honey is a mixture of various types of sugar compounds and it has identical properties throughout and cannot be separated into its components. So, you can say that honey is a homogeneous mixture.

Chemical and physical properties Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen.

All matter can be classified as either a substance or mixture. A substance is an element or a compound. A mixture is heterogeneous or homogeneous….

Drinking alcohol (ethanol) is a not a mixture, but a pure substance that happens to be a liquid at room temperature and typical atmospheric pressure. It’s about 43% ethanol, the rest is mostly water (which makes it a mixture).

Glucose (C6H12O6) is an organic compound composed of the elements carbon, hydrogen and oxygen. It is a pure substance, not a mixture.

Distilled spirits (whisky, gin, vodka) usually contain 40–50% ethanol; wines contain 10–12% ethanol and beer ranges from 2–6% ethanol, while standard lager contains about 4% ethanol. Numerous over-the-counter medicinal or cosmetic products can also contain significant percentages of ethanol (10–40%).

Vodka, by definition, is ethanol cut with water to at least 80 proof (40 percent purity). More often, commercial vodkas are fermented and distilled from wheat, rye, or corn.

How Dangerous Is It to Consume Rubbing Alcohol? When it comes to drinking rubbing alcohol, the digestive tract suffers the most, even when only swallowing a small amount. The body metabolizes these extremely high alcohol levels into acetone. If consumed to intoxication, the substance can lead to organ damage.

If you are having trouble finding rubbing alcohol, then you can substitute a white ethanol like vodka or everclear. Remember, proof and percentage of alcohol are different. To get a drinking alcohol with at least 60% alcohol, you need to get alcohol that is 120 proof.

Turns out vodka can be used for many of the same tasks as vinegar, such as degreasing, deodorizing and disinfecting. Green cleaning experts say it’s a great choice for anyone sensitive to smell.

Even though ethanol is very commonly used, it is a dangerous chemical. While ethanol is consumed when drinking alcoholic beverages, consuming ethanol alone can cause coma and death.

Solutions of at least 3 percent hydrogen peroxide make efficient household disinfectants. Don’t dilute. As with rubbing alcohol, first wipe down the surface with soap and water. Use a spray bottle or a clean rag to apply the hydrogen peroxide to the surface.

Water (distilled is recommended because you want your water to be free of any possible contaminants) . 25 kilograms of Sugar per liter of water. 1 packet of Yeast for every two liters of water.

If you are using a 70% isopropyl alcohol you need to change the proportions to this:

1. 7 tablespoons plus 1 teaspoon of 70% isopropryl alcohol.
2. 2 teaspoons aloe vera gel.

For example, vinegar does a decent job removing dust and water spots, but it doesn’t cut through a lot of sticky stuff, and it tends to streak more than other cleaners. Rubbing alcohol is a potent cleaner but it’s harsh and strong-smelling so it’s not a great glass cleaner by itself.

Vinegar is a strong acid with amazing uses, BUT rubbing alcohol is better for all-purpose cleaning. Remember rubbing alcohol can be used on any surface to clean it. Vinegar is acidic, so it can’t be used on everything!

While most hand sanitizers contain either ethyl alcohol or isopropyl alcohol, alcohol-free hand sanitizers are also for sale. These usually contain antimicrobial compounds like benzalkonium chloride that provide a lasting protection against bacteria.

You can clean most surfaces by spraying or wiping rubbing alcohol on them. However, don’t apply alcohol to permeable materials like quartz and granite. Plastic laminate and sealed marble are fine. Cleaning jewelry.
