SAT Natural Sciences
catalyst [noun]

(chemistry) a substance that causes a chemical reaction to happen at a faster rate without undergoing any chemical change itself

Ex: In the Haber process , iron is used as a catalyst to promote the synthesis of ammonia from nitrogen and hydrogen gases .
buffer [noun]

a solution containing a weak acid and its conjugate base, or a weak base and its conjugate acid, which maintains a stable pH when small amounts of acid or base are added

Ex: Pharmacists prepare buffers to ensure the stability of medicines during storage .
reactant [noun]

a substance that takes part in and undergoes a chemical reaction, leading to the formation of new products

Ex: The reactants in the process of burning wood are wood and oxygen .
reagent [noun]

a substance or compound used in a chemical reaction to detect, examine, or produce other substances

Ex: The forensic lab uses specific reagents to test for the presence of illicit drugs in samples .

any of the elements in Group 18 of the periodic table, including helium, neon, argon, krypton, xenon, and radon, characterized by their inert nature and stable electron configurations

Ex: Argon , a noble gas commonly used in welding , provides an inert atmosphere to prevent the oxidation of metals during the process .

a group of non-reactive gases that typically exhibit low chemical reactivity due to their stable electron configurations

Ex: Inert gases such as neon are used in neon signs to produce characteristic bright colors when electrically charged .
halogen [noun]

a type of chemical element found in Group 17 of the periodic table, known for being highly reactive and commonly used in disinfectants and lights

Ex: Bromine , a halogen with properties similar to chlorine , is employed as a disinfectant in swimming pools and hot tubs .

a durable plastic material used for packaging, bags, and various applications

Ex:

a lightweight and versatile synthetic polymer used in packaging, insulation, and disposable products

Ex: Artists sculpt intricate designs using polystyrene due to its ease of shaping and lightweight nature .
phosphorous [adjective]

referring to the essential chemical element phosphorus, which is vital in biological processes and various industrial applications

Ex: The phosphorous content in bones contributes to their strength and structure .
acetone [noun]

a colorless, volatile liquid solvent commonly used for removing nail polish and other substances from surfaces

alginate [noun]

a naturally occurring polysaccharide derived from brown seaweed, commonly used in various industries for its thickening, gelling, and stabilizing properties

silicate [noun]

a compound containing silicon and oxygen atoms, often forming minerals or glasses, with diverse applications in industry and nature

Ex:
graphene [noun]

a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, known for its exceptional strength, electrical conductivity, and flexibility

a naturally occurring organic compound found in many fruits that contributes to their sour taste

a weak organic acid found naturally in citrus fruits like lemons, oranges, and limes, commonly used as a food additive for flavoring and preserving

Ex: Many soft drinks and candies include citric acid to enhance their taste .

a chemical compound that contains phosphorus and oxygen atoms, commonly found in salts or esters of phosphoric acid, important for biological processes and industrial applications

Ex: The doctor recommended a diet rich in phosphates to strengthen bone density and prevent osteoporosis .

a type of elementary particle that is one of the six types, or flavors, of quarks that has an electric charge of +2/3 and participates in strong and electromagnetic interactions

Ex: Charm quarks are known for their relatively short lifetime , decaying into more stable particles within a fraction of a second after their creation .

something that has specific chemicals or causes a chemical reaction that destroys harmful microorganisms such as bacteria

a chemical compound important for regulating pH balance, found in baking soda and crucial for bodily functions

Ex: Bicarbonate in the blood acts as a buffer against acids , ensuring stable pH levels .
solute [noun]

a substance that is dissolved in a solvent, resulting in a solution

Ex: Carbon dioxide ( CO2 ) dissolving in soda is an example of a gas solute in a liquid solvent .
saturated [adjective]

having absorbed as much of a substance as possible at a given temperature, reaching its maximum concentration

Ex:
ethereal [adjective]

(of a solution) containing volatile or highly flammable substances, such as diethyl ether

Ex: The compound 's ethereal aroma indicated the presence of volatile organic compounds .
inorganic [adjective]

describing chemical compounds that do not contain carbon-hydrogen bonds and are typically derived from minerals or non-living matter

Ex: Inorganic acids such as sulfuric acid are essential in chemical manufacturing processes .
solvent [noun]

a liquid that is capable of dissolving another substance

Ex:
alkaline [adjective]

refering to substances that have a pH greater than 7, indicating a basic or non-acidic nature

Ex: Baking soda ( sodium bicarbonate ) is slightly alkaline and is used in baking and as a household cleaner .
saline [adjective]

containing or relating to salt

Ex:
