Determining Acids and Bases With Homemade pH Indicator Strips Made With Red Cabbage Juice Period 0 IB Chemisty Annie Truong Ms. Tran Purpose: The purpose of this lab is to make homemade pH indicator strips using red cabbage juice as the main ingredient and estimate the pH of different substances with these strips. Background Information: Acids and bases have properties of modifying the color of certain substances. The juice of the red cabbage is a blue-violet color and when it comes in

Solving Part A: Center of Mass in One Direction 1. Since the mass of the plate is a uniform‚ the center of mass is in the center of the plate. The plate has diameter d = 28 cm‚ thus the center of mass is 14 cm from the edge of the plate. In the lab‚ two scenarios will be analyzed; 1) when the glass is standing up‚ and 2) when the glass is laying on its side. When the glass is standing up‚ its mass is uniform about the axis of symmetry. Therefore‚ the horizontal center of mass will be at the exact

Lab 1 – Measurement of Space and Time Anthony Lucci Lab Partner: Amy Hayes Question 4: Both the height and diameter of the cylinder were taken to find the volume; five times for both measurements. Vernier calipers were used to get these measurements by clamping the cylinder between the jaws of the calipers. By looking at the mark of the zero‚ in relation to the main scale‚ the line best lined up with a line from the main scale was taken down. Getting

Argumentation Documentation In this lab‚ the goal was to create a ‘rocket’ out of a pipette and to determine the right ratio of Hydrogen to Oxygen to Water in order to generate the maximum possible flight distance. My partner and I arrived at our ratio of 1.5:3:1.5 (H2:O2: H2O) because of its consistency‚ high distance‚ and a bit of gut feeling. We had a few ratios that worked pretty well including 2:3:1 and 2.5:2:1.5 (see graph/chart)‚ but we chose ours because it felt like a good decision‚ and
