most simple bath bomb recipes have: baking soda‚ citric acid‚ and cornstarch. When baking soda and citric acid are mixed together with some water‚ they undergo a chemical reaction. Specifically‚ this reaction involves acid-base chemistry‚ since the baking soda—also known as sodium bicarbonate (NaHCO3)—is a weak base‚ and citric acid (C6H8O7) is a weak acid. This reaction is shown in Equation 1‚ below. As you can see from Equation 1‚ the acid-base reaction produces carbon dioxide (CO2) gas. This gas

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater

as people not enemies. King spoke of our complete funding handed to the French so they may advance in control of these people. “He proclaimed that America is a victim of Western arrogance for rejecting the revolutionary government seeking self determination in Vietnam” (Spence‚ 2009). King told us their story of devastation. He described our destruction of their resources. War efforts contributed to the loss of crops‚ tainted water supplies‚ and the demoralized the Vietnamese people in their efforts

Blackbody radiation: a spectroscopic study John Greavu Partner: Nicholas Souhleris TA: Yilikal Ayino (Friday‚ Section 006) April 18‚ 2014 I. PRELAB A blackbody is a body that absorbs all electromagnetic radiation and emits a continuous spectrum‚ such as heated cavern with just a small opening to the outside world. In 1900‚ German physicist Max Planck derived an expression for this blackbody spectrum. Knowing that oscillators emit radiation‚ he assumed that oscillators within the cavern were

Acid Base Titration bre’ana March 1‚ 2013 Purpose: The purpose of this experiment is to determine the concentration of a solution of NaOH by titration with a standard solution of HCl. It was also the purpose to determine the concentration of a sample of white vinegar by titration with a standard solution of NaOH. Introduction: Using the method of titration is how the experiment gets to the conclusion of the concentration of a solution. When doing this experiment‚ measurement is very important

Sugar maples‚ red oaks‚ sumac‚ birch and other trees and shrubs turn from green to bright red‚ orange‚ and yellow. The short‚ cool days of autumn bring an end to the production of chlorophyll (the green light-gathering pigment). As chlorophyll gradually breaks

The experiment is based on the fact that all acids in the experiment have a unique Ka value. However‚ the only difference between the possible acids is the number of chlorine atoms attached to the carbon atom that is not in the functional group. The reason for the number of chlorine atoms attached to the carbon atom affecting the Ka is that there is a large electronegativity difference between chlorine and carbon‚ pulling the electrons to tend to the chlorine side. This forms a domino effect where
