Percent Acetic Acid in Vinegar Introduction: Acetic acid is reactive when combined with calcium carbonate. In this lab‚ we will use vinegar for its acetic acid and egg shells for their calcium carbonate. Marketable vinegar differs in its acetic acid concentration from 4-6%. Calcium carbonate reacts with the acetic acid in vinegar to produce carbon dioxide‚ water‚ and calcium acetate as represented by the equation: CaCO3 + 2HC2H3O2 CO2 + H2O + Ca(C2H3O2)2. The calcium carbonate reacts with

Osmosis and the Egg Lab Report By: N. Mullins Date: January 20‚ 2011 Introduction This lab was designed to explain the different things osmosis does. Osmosis is the diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually

Philippine Education for All 2015: Implementation and Challenges Education is very important to human. We need to be educated in order for us not to be fooled by someone. Our parents send us in school to learn the basic skills specifically reading‚ writing‚ and simple arithmetic because they believe that education is the only treasure that they can give to us. It is also an instrument to elevate our social status in life. That’s why our government is trying to think of an effective way to

The shell project Our teacher gave the class a project that was about shells and burning them with vinegar. All of us started to put the shells in the vinegar in Tuesday. Then we waited till Thursday the 3rd shell in my teams cup was already dissolving. After seeing on what happened to the shells being in the vinegar for a few days me and my team worked on the weight the shells were. We did graphs‚ charts a lot of work and so little time‚ but we kinda almost completed it‚ I mean one of my

will start seeing quite a few sales on eggs. Why? Eggs are one of the main staples in the Easter holiday tradition. Everyone gets together the night before Easter and colors their eggs a wide range of colors to put in their Easter baskets for the Easter Bunny to hide. An egg seems like such a simple food item‚ very few people ever wonder what all had to happen in order for them to be able to buy their eggs from the grocery store. If there were suddenly no eggs to color for Easter I am sure everyone

Who’s been cheating on the vinegar? Aim: To investigate if the vinegars have been diluted by working out their concentrations. Scientific Background: Vinegar is an acid and there fore can be neutralised by an alkali. Acid + Alkali à salt + water Hydrochloric acid + Sodium Hydroxide à Sodium chloride + water Vinegar is a weak acid and therefore it only partially ionises in solution. CH3COOH ßà CH3COO- + H+ An alkali such as Sodium Hydroxide has a formula NaOH. If the alkali

structure of proteins. We used a raw egg and noted the changes that happen when there were changes in temperature‚ pH levels‚ and salinity. Five eggs were cracked open and placed into different bowls with different solutions placed into each bowl. What we looked at was the process of denaturing of proteins seeing how it affected the composition of the raw egg between the yoke and white portion. My hypothesis for this experiment is: Solution 1 will case the egg to denature and separate‚ Solution 2

“Egg Baby” – What did I learn by caring for mine? This project gave me a sneak peak on what it’s going to be like as a parent‚ but not even close to the real thing. At first I thought this project was going to be a breeze‚ but once I got into it I was all wrong. Taking my egg‚ Lily‚ everywhere with me was a pain. I had to worry about her “baby seat” and make sure it was safe for her. Going through the crowded halls at school was quite difficult also. I had to make sure she was close by my
