Chem Flashcards
The substance that dissolved in the solvent ?
Solute
When alcohol is used as a solvent the solution is termed as what?
Tincture
An example of a tincture and is used to kill bacteria and prevent infection at the site of a wound is?
Iodine
Are formed when two substances have opposite polarities are mixed ?
Emulsifications
As the temp of a solvent decreases, what decreases causing less space between the solvent molecules and in which the solute can dissolve ?
Solubility
Properties that change with the addition of a solute to a solvent. Two of these properties are melting point and boiling point
Collective properties
Are made of hydrogen and carbon, ringed compounds is simple
Aromatics, the compound is called benzene it has six carbon aromatic
Common organic compounds:
Carbon,hydrogen, nitrogen, alcohols, ketones, esters, amines, carboxylic acids, aldehydes, ethers, sulfur
Important element needed to help proteins and enzymes maintain structure
Sulfur
Compounds that have the same molecular formula but different structures
Isomers
Organic compounds are the basis for life as we know it because ?
Carbon-carbon bonds are strong
Carbon can form long chains
Carbon chains can include other elements to give rise to different functional groups
Conduct electricity in solution
Electrolytes
The most common acid base reaction
Neutralization reaction
Acid and base react to form a salt and water
Examples of acids that react with active metals to form a hydrogen gas
Zinc and magnesium
Metals that do not lose an electron to hydronium ions
Gold and silver
Explains why they never tarnish and react with other substances
Indicates just how acidic or basic a solution is
Ph
Substances that are added to a solution so that the solution resists change in ph, many medications are designed to have this to protect the lining if the stomach
Buffers
Preformed to determine the concentration of an acidic or a basic solution. During this process an acid or base is added to the solution so that either the acid or base neutralize each other
Titrations
The higher ______ causes molecules to collide more frequently and with more energy as to initiate the reaction faster
Temperature
Having substances chopped up into finer powders exposes more of the surface area of the substance. The reaction then takes place faster than if the substance were in one place
Surface area
Higher__________ causes molecules to collide more frequently
Concentration
Although not effective for solids or liquids, increasing the ________ on a gas causes more gas molecules to collide more frequently as they are packed more tightly together
Pressure
Homogeneous mixture that combines a solute and solvent together?
Solution
