GROUP MEMBERS:. Ajit. Singh Patel. Kuldeep. Singh. Reyad. . Ranjon. Roy. BACKGROUND AND OBJECTIVE. :. BACKGROUND:. Sources of arsenic. Why is its removal necessary?. Methods for removal. OBJECTIVE. Chemistry . Acids and Bases. Properties and pH. Chemical Warfare!. What is an Acid?. 3 Major Definitions: Arrhenius, Bronsted-Lowry, and Lewis.. Arrhenius and Bronsted-Lowry say an acid is:. A proton donor. _____ . is a chemical compound that increases the concentration of ________________ ions (H. +1. ), in aqueous solution. The hydrogen ions are attracted to the water molecules in an aqueous solution and form . 1. 2. Liquid Dosage Forms. Solution: . solutions are clear Liquid preparations containing one or more active ingredients dissolved in a suitable vehicle.. . Suspension:. (Solid in Liquid dispersion) Liquid preparations containing one or more active ingredients suspended in a suitable vehicle.. condition. However, to adjust solution pH by using acidic species results in undesirable species, which will affect the treated water quality. According to the study earlier [17], the above issue of c A. Naming Acids and Bases . 6.1 Theories of Acids and Bases. . Section 6: Acids & Bases. . Rules. 1. hydrogen becomes acid. 2. hydrogen becomes acid. What is an Acid?. A solution with an excess of H. +1. ions. How do we know that a chemical is an acid?. Most Acids start with an ‘H’ in their chemical formula. What are the properties of an Acid?. The . Brønsted. -Lowry Definition of Acids and Bases. 1. . Acid. is a substance that can donate (or lose) a . proton. ; . Base. is a substance that can accept (or remove) a . proton. ..  . 1) . Hydrogen chloride, a very strong acid, transfer its proton to water.. ”. Properties of Acids. They taste . sour. (don’t try this at home).. They can . conduct electricity. .. Can be strong or weak electrolytes in aqueous solution. React with metals. to form H. 2. Solute Concentrations, Molarity. Solution: . homogeneous mixture of two or more substances. Solute. : . the substance being dissolved. Solvent. : . the substance doing the dissolving. Concentration. . A beaker of aqueous solution has a pH of 7.2 and the desired pH is 9.4. Should an acid or base be added?. Base, because to increase the pH, the H. +. needs to be at a lower concentration. Bases will either increase the OH. Topics 5 and 6 . May 4-6, . 2020. .
