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

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased

Abstract By using acid-base titration‚ we determined the suitability of phenolphthalein and methyl red as acid base indicators. We found that the equivalence point of the titration of hydrochloric acid with sodium hydroxide was not within the ph range of phenolphthalein’s color range. The titration of acetic acid with sodium hydroxide resulted in an equivalence point out of the range of methyl red. And the titration of ammonia with hydrochloric acid had an equivalence point that was also out of

The identification of acids and bases using a natural indicator Purpose: The purpose of this lab practice is to identify the pH of certain solutions and if they are acids or bases. Introduction: In chemistry‚ pH is a measure of the activity of the (solvated) hydrogen ion. p[H]‚ which measures the hydrogen ion concentration‚ is closely related to‚ and is often written as‚ pH. Depending on the pH solutions will be acids or bases. An acid is a chemical compound that dissociates in solution‚ releasing

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

New Military Base There are many types of military bases; some have piers for ships and submarines‚ others have air strips for planes and others provide training for military members. A new military installation can provide employment opportunities for community members. A military base can increase the revenue generated by local businesses‚ create job opportunities for locals and even add revenue to our local government. A military base will be a good addition to the community. A new
