Acid: A chemical substance (typically‚ a corrosive or sour-tasting liquid) that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red. Ionic Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A

a liquid ketone which was distilled or boiled to find the boiling point and then identified using a chart of unknown identities and boiling points. The oxidation of the unknown alcohol was done through the mixing of the unknown alcohol‚ glacial acetic acid‚ and bleach. Through the procedure of oxidation over a period of two lab days‚

Lab 5 Acid/Base Extractions Introduction The purpose of this experiment is to separate either the organic base (amine) or organic acid (carboxylic acid) from a mixture that contains inorganic impurities (salt) by performing a liquid-liquid extraction and then taking a melting point. Key Experimental Details and Observations Our starting material‚ Compound B‚ was a fine white powder and weighed 0.535g. The final product was a shiny white sheet that resembled acrylic paint and weighed 0.109g

When the volume of vinegar was increase‚ more sodium bicarbonate reacted and more CO2 was produced. The percent by mass of the reached sodium bicarbonate rose with increasing amounts of vinegar. The limiting reagent is baking soda from 25-35 ml while acetic acid is the excess. The percent by mass reacted sodium bicarbonate in the tablet increased with

The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of two methods‚ green chemistry is the effective method because reduce the consumption

Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

Every solution has either has an acid or basic trait. The acid or basic trait in a solution are called pH level. pH is a scale that is used to determine if solution is acidic ‚basic‚ or neutral. During Living Environment class‚ we conducted a experiment that allowed us to measure the pH levels of 3 solutions. We were split into groups and each person had to bring a household solution from around the house. There certain materials that were needed to conduct the experiment .The following
