Cell respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available by the following equation: All orga...

Temperature changes have profound effects upon living things. Enzyme-catalyzed reactions are especially sensitive to small changes in temperature. Because of this, the metabolism of poikilotherms, organisms whose internal body temperature is determin...

In this experiment, you will monitor conductivity during the reaction between sulfuric acid, H2SO4, and barium hydroxide, Ba(OH)2, in order to determine the equivalence point. From this information, you can find the concentration of the Ba(OH)2 solut...

A common analysis of a weak acid or a weak base is to conduct a titration with a base or acid of known molar concentration to help determine the equilibrium constant, Ka, for the weak acid or weak base. If this titration is conducted very carefully a...

The reaction of ethyl acetate and hydroxide ions yields ethanol and acetate ions, as shown below. The progress of this reaction can be observed by monitoring the conductivity of the reaction mixture. Although the reactants and products each co...

The evaporation of a volatile liquid from the surface of a Temperature Probe is an endothermic process that results in a temperature decrease. The magnitude of a temperature decrease is, like viscosity and boiling temperature, related to the strength...

Thin-layer chromatography (TLC) is an important technique in organic chemistry. TLC uses the different affinities a compound has for the mobile and stationary phases to achieve separation of mixtures of organic compounds. TLC can also be used to iden...

The aldol condensation is a reaction between two aldehydes or ketones, catalyzed by a base or acid, generating a molecule having both alcohol and aldehyde functional groups. The aldol product is either a β-hydroxyaldehyde or a β-hydroxyketone. This...

In this experiment, you will observe the formation of four acids that occur in acid rain: carbonic acid, H2CO3 nitrous acid, HNO2 nitric acid, HNO3 sulfurous acid, H2SO3 Carbonic acid occurs when carbon dioxide gas dissolves in rain drop...
