    One can find an empirical formula by taking a sample of a compound and dividing the  number of moles of one element in the compound by the number of moles of another element in  the compound to form a small whole­number formula. For example‚ in a sample of a made up  compound of oxygen and lead‚ one mole of lead has a molar mass of 207.2 g/mole‚ and oxygen  has a molar mass of 16 g/mole. If this compound forms in a one to one atom ratio‚ then the ratio  of moles will be 13 moles of oxygen to 1 mole of lead.     In the experiment‚ the students

    Title: Acids‚ Bases & Buffers Objectives: 1. To understand the acid-base chemistry. 2. To prepare and evaluate a buffer system 3. To measure the buffering capacity of two types of isotonic drinks. Introduction: There are acid-forming‚ basic forming and neutral food‚ however the acid or alkaline properties of a food is unable to judge by the actual acidity of the food itself. For example‚ citrus fruits such as lemon are acidic‚ but they are alkaline-forming when we consume and digest it. Therefore

    INTRODUCTION Differences between acids and bases An acid-base reaction is based on the reaction involving the ionization of water H2O -> H+ + OH- This means that water can break apart into a hydrogen ion and a hydroxide ion. These two ions can also join together to form a water molecule. When a strong acid is placed in water‚ it will ionize completely‚ and break down into its constituent ions in which one of it a hydrogen ion. When a strong base is placed in water‚ it will ionize
