LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Margaret Sanger was a very important and influential person of her time. Back then‚ women were often mistreated and had many unwanted pregnancies. Lacking effective contraceptives‚ these women resorted to unsafe and cheap abortions. Margaret Sanger wanted to help women gain planned parenthood while using safe and legal birth control methods.

Critically discuss the power of the state and its relevance to the Unitary perspective. Address this by analysing other frames of reference within Fox (1966) theory‚ other models‚ theories and legislation relating to the implications of how conflict and harmony are managed within organisations. There are three factors that influence the behaviour of organisations‚ the individuals that interact with employment relations‚ managers‚ employees and the state. The state‚ defined‚ is the government chosen

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.
