Measuring Ph Levels Coursework Example

Name: Date: Instructor’s Name: Assignment: Title: Measuring pH Levels Abstract Acids and bases are common in several household applications especially in our kitchens. Different methods are used to determine whether a substance is acidic or base. The methods include the use of litmus paper and measuring of pH. The pH of a substance also tell about the strength of the base or the acid. The pH scale ranges from 0 to 14. Acids have a pH of less than 7 while the bases have a pH of more than 7. Any substance with a pH of 7 is neutral. In this experiment, we will discuss how to read the pH of different substances and identify different types of bases and acids found in around our homes. Additionally, we will determine the pH levels of different samples of water from different lakes. We will also discuss the causes of acid rain, the acidity in the lakes and the impacts of acidification on the environment. Part I: Answer the following questions while in the Unit 1 lab environment. Section 1: You will be testing 4 known solutions for pH levels using a standard wide-range indicator. Based off of the results obtained in the lab room, fill in the following table: Solution Number pH from Lab Acid, Base or Neutral? Solution Name (what was in the test tube?) Solution 1 7 Neutral Pure Water Solution 2 2 Acid Lemon Juice Solution 3 12 Base Beach Solution 4 5 Acid Coffee Section 2: Now that you understand how to read pH measurements, go out into the field to gather pH samples from 3 different lakes to take back to the lab for testing, and answer the following questions: What was the pH level measured at Lake 1? The pH of the sample from Lake 1 was 6. What was the pH level measured at Lake 2? The pH of the sample from Lake 2 was 3. What was the pH level measured at Lake 3? The pH of the sample from Lake 3 was 5. Which two lakes have the highest levels of acidity in their water? The pH results of the water samples from th...
