Acetone should not be stored in the same chemical store as bromine, chlorine, nitric acid, sulfuric acid, or hydrogen peroxide.
Raw food and cooked food should be stored separately in the fridge. Bacteria from raw food can contaminate cold cooked food, and the bacteria can multiply to dangerous levels if the food is not cooked thoroughly again. Always store raw food in sealed or covered containers at the bottom of the fridge.
For example, both nitric and perchloric acids are incompatible with organic acids (such as acetic acid) and should not be stored together. Most labs have limited space, but the following priorities may help you decide how to store the chemicals.
Mixture. A mixture is a combination of two or more pure substances that do not chemically combine. Mixtures do not have a constant composition and can be created with varying ratios of the substances. Mixtures can be further classified as homogeneous or heterogeneous.
Chlorine and ammonia should be stored separately from each other, as well as from all other chemical groups.
Hydrogen Peroxide reacts violently with FINELY DIVIDIED METALS; REDUCING AGENTS; COMBUSTIBLES; STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE); OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE); ORGANICS; ALCOHOLS; ETHERS; KETONES; ...
Acids: Organic acids should be kept separate from inorganic (mineral) acids. For example, store acetic and formic acids separate from hydrochloric and sulfuric acids.
Corrosive substances and flammable liquids must not be stored together. If these two classes of dangerous goods must be stored in a common dangerous goods store, they must be kept apart.
Keep Cauliflower Away From Apples, Kiwis, and Onions
Cauliflower is a vegetable that belongs away from most fruits and alliums. "Cauliflower is very ethylene sensitive, so it is best not to store it in the same drawer as apples, melons, kiwis, or onions," says Adler.
Potassium Hydroxide is not compatible with REDUCING AGENTS (such as LITHIUM, SODIUM, ALUMINUM and their HYDRIDES); WATER; HALOGENATED HYDROCARBONS (such as METHYLENE CHLORIDE and TRICHLOROETHYLENE); ORGANICS; NITROCARBONS; and AMMONIUM SALTS.
Here are a few examples: Oil: Non-polar substances like oil do not mix with water because water is a polar molecule. Oil and water are immiscible, meaning they do not form a homogeneous mixture when combined. Mercury: Mercury is a metal that is liquid at room temperature and does not mix with water.
A mixture is a material system made up of two or more different substances, which are mixed but not combined chemically.
An element is a pure substance that cannot be separated into simpler substances by chemical or physical means.
For example, acetic acid and ammonium hydroxide both start with “A” but are incompatible with each other, and should not be stored together.
General Storage Requirements
All chemicals must be stored in a safe, secure location. Hazardous chemicals must be stored below eye level. Do not store chemicals on the floor, window ledges, or balconies. Keep containers closed unless you are dispensing a chemical or adding to the container.
General Reaction
An acid and a base react with each other. Generally, the product of this reaction is salt and water. Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat.
Acids — Important: Segregate acids from chemicals which could generate toxic or flammable gases upon contact (e.g., cyanide salts, metal sulfides, calcium carbide) and reactive metals (e.g., sodium, potassium, magnesium). Store in a ventilated corrosive storage cabinet if possible.
Keep apart solid and liquid products, flammable and non-flammable liquids; acids and alkalis etc. Store all flammable substances in a flameproof metal cupboard. DON'T let your storage space get too hot - this can alter the products' chemistry and reduce their efficicacy.
