Base (chemistry) Base (chemistry) In chemistry, bases are substances that, in aqueous solution, release hydroxide (OH) ions, are slippery to the touch, can taste bitter if an alkali, change the color of indicators (e.g., turn red litmus paper blue), react with acids to form salts, promote certain chemical reactions (base catalysis), accept protons from any proton donor or contain completely or partially displaceable OH ions. Examples of bases are the hydroxides of the alkali metals and the alkaline earth metals (NaOH, Ca(OH), etc., see alkali hydroxide and alkaline earth hydroxide). These particular substances produce hydroxide ions (OH) in aqueous solutions, and are
A. Philip Randolph Career Academy the application of matrices to the solution of linear systems is also included. Active Physics- an introductory physics course that studies matter and energy. Basic principles of physics are explained. An understanding of physical laws and their relationship to everyday events will be stressed. Biology - (10th and 11th) - develops an understanding of living things. Topics include the chemistry of life, cell structure and genetics, thermal, and behavior of fluids. Chemistry - (11th) - a course that teaches the composition and structure of matter. Environmental Science- a course teaching environmental concepts and how they affect the sustainability of ecosystems.
