Lab Report: pH Solutions
September 26, 2014

Introduction: In this lab we measured pH using a variety of methods and materials. After the solutions we tested them with an indicator. By using the indicator we developed a concept of how each solution differed in relation to the pH scale.

Material/Methods:
Water: We used indicator paper to determine its pH. When tested by placing the indicator paper in the water, we found out that water has a neutral pH because it turned the indicator paper yellow.
Hydrochloric Acid: We used indicator paper to determine its pH. When tested by placing the indicator paper in the hydrochloric acid, we found out that hydrochloric acid has a acidic pH because it turned the indicator paper red.
Sodium Hydroxide: We used indicator paper to determine its pH. When tested by placing the indicator paper in the sodium hydroxide, we found out that sodium hydroxide has a basic pH because it turned the indicator dark blue.
Ammonium Hydroxide: We used indicator paper to determine its pH. When tested by placing the indicator paper in the ammonium hydroxide, we found out that ammonium hydroxide has a basic pH because it turned the indicator dark blue/green.
Sulfuric Acid: We used indicator paper to determine its pH. When tested by placing the indicator paper in the sulfuric acid, we found out that sulfuric acid has a acidic pH because it turned the indicator red.

Lab Report Format

ANATOMY & PHYSIOLOGY CLASS: WRITING LAB REPORTS The following is an explanation of the format that is to be used for writing lab reports. There will be lab activities for each Chapter in the textbook. 1. Lab Report grades are given the same value as a test grade. It is very important that they be done correctly and thoroughly. 2. All lab reports should be typed using Times New Roman and only 12 font. (no exceptions) 3. In the upper left hand corner include your name, high school, and A & P…

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason, you are required to thoroughly read through the experiment information presented in the lab manual, and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab, I will not allow you to enter the lab and you will receive…

Drosophila Lab Report

Drosophila Lab Report By Logan Aker University of Colorado, Boulder Principles of Genetics Lab, MCDB 2151, Tuesday 4 – 5:50pm TA: Alexander Martinez Abstract In this lab, we carried out two different crosses using Drosophila; a monohybrid cross and a sex-linked cross. This lab specifically tested Mendel’s laws of independent assortment and the law of segregation in genetics. We selected males and females of two different phenotypes and mated them (and their succeeding offspring)…

Momentum Lab Report

Lab report #5 In this experiment, we used a nearly frictionless surface to compare velocity characteristics to that of momentum, suing different weights, as well as bouncing carts and sticking carts together. This is important to understand, because momentum is a combination of weight and velocity, where as velocity is independent of weight. The materials we used for this experiment include 2 carts, with weights of 139.7 grams and 290.4 grams. We also used springs on the ends to “bounce”…
