Lab Report: Hard Water Purpose: The purpose of this lab is to determine whether a liquid is hard water or not. Background: Hard water is the water that has a high amount of mineral in it‚ usually Ca2+ and Mg+. These cations enter the source of water by leaching from minerals within a wet underground layer of water- bearing rock‚ or an aquifer. According to the WHO‚ hard water is not harmful to human’s health but it’s a serious problem in the water industry. Household plumbing and appliances

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Condensation and evaporation are represented in the model. Condensation formed inside the jar and under the lid and the warm water evaporated. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Precipitation and infiltration did not get represented

Water Quality Testing Pre-Lab Mrs. Susil-APES You and a partner will be performing water quality tests on water that you collected from a canal‚ lake‚ or pond. This lab will take two days to complete. You must wear proper laboratory attire (closed toed shoes‚ goggles‚ aprons‚ gloves) in order to participate in this lab. We will meet in the classroom across the hall from 8154. Numbers 1-4 below are due before the lab begins on Wednesday in your lab notebook: 1. Title

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

The intention of the “Foul Water” lab was to purify a sample of sewage water and conserve as much as possible. The water should be clean enough to wash your hands with. My hypothesis is that the water will be cleaner than the initial water sample‚ but not to the standard that I would wash my hands with. Significant terms to know include purification‚ filtration‚ adsorption‚ volume‚ clarity‚ dissolved‚ filtrate‚ impurities‚ pipette‚ clay triangle‚ funnel cone‚ iron ring‚ beaker‚ and Erlenmeyer flask

This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about

drinking water samples from different places using four of the standard drinking water tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan

purpose of this lab was to practice measuring the mass and volume of different samples and to calculate the density and specific gravity of those samples using the measurements. B. Equipment 1. Electronic balance- The electronic balance is a device used to measure the exact mass of an object 2. Graduated cylinder- The graduated cylinder is a tool used to measure the volume of a liquid 3. Pipets- Pipets are small tubes that suck up and contain liquids C. Technique 1. The water displacement technique

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

polluted water so the water will have a clarity of 0%. If a filter is built for the polluted water‚ then the waters clarity will be 0% and the pH value will be 7. The purpose for this lab is to get the polluted water to a clarity of 0%. Water pollution is playing a major role in today’s ecosystems because the water is becoming unsafe to live in and unsafe to consume. “Water pollution is any physical or chemical change in water that adversely affects organisms” (Chiras‚ 2015).
