Problem: How do protease in some fruit juices help softening meat? Hypothesis: The protease in some fresh juices digests collagen‚ which gives meat a tough texture by holding meat fibres together. Design of investigation: In order to test the hypothesis‚ the presence of protease in those fresh juices was tested at first. Then the amount of them was needed to be compared for finding their difference in effectiveness in tenderizing meat. Control experiments were set up for proving protease was

Lab #16: Gravimetric Analysis of Metal Carbonate Introduction: In this laboratory the identity of group 1 metal Carbonate is determined gravimetrically using a double replacement precipitation reaction. Concepts: Double-Replacement reaction Gravimetric analysis. Background: The identity of group 1 metal M is determined by analyzing an unknown Group 1 metal carbonate‚ M2CO3. There are 3 main reactions in this lab: 1. Equation 1: M2CO3 (s) → 2M+ (aq) + CO32- (aq) 2. Equation 2: Ca2+

TITLE Basic Technologies of Handling Chemicals and Laboratory Apparatus INTRODUCTION Density is defined as mass per unit volume. The commonly used unit to indicate the density of water is (g/cm3). Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1 g/cm3 at 4oC. When the temperature changes from either greater or less than 4oC‚ the density will become less than 1g/cm3 only when it is pure water. Other factors that
