Acid-Base Titration Objectives: 1. To titrate a hydrochloric acid solution of unknown concentration with standardized 0.10M sodium hydroxide. 2. To utilize the titration data to calculate the molarity of the hydrochloric acid. Materials: See handout for more info. Procedure: See handout for more info. Data and Calculations: Table 1: Volume of NaOH Required to Neutralize 10.00mL of Unknown HCl Molarity of NaOh | Trial 1 | Trial 2 | Trial 3 | Trial 4 | Initial Volume of NaOH(mL)

Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain‚ snow‚ hail‚ or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries‚ coal burning factories‚ power plants and automoble engines

an environmental stimulus and a naturally occurring stimulus. It ’s important to note that classical conditioning involves placing a neutral signal before a naturally occurring reflex. In Pavlov ’s classic experiment with dogs‚ the neutral signal was the sound of a tone and the naturally occurring reflex was salivating in response to food. By associating the neutral stimulus with the environmental stimulus (the presentation of food)‚ the sound of the tone alone could produce the salivation response

Experiment #5: Acid Burn!!! Introduction The goal of this lab was to correctly prepare a 0.2M solution of NaOH‚ identify highly acidic household cleaning chemicals‚ and determine their concentration (molarity) through titrations using the previously prepared 0.2M NaOH solution. Experimental First‚ to create 0.5L of 0.2M solution of NaOH‚ standard 3M NaOH solution was obtained. Next‚ calculations were performed to determine the amount 3M NaOH necessary to create 0.5L of the 0.2M solution and‚ as

The book‚ "Stuck in Neutral" by Terry Trueman is a very touching story. A story I think people should be sharing more with others. Stuck in Neutral is about a fourteen year old boy named‚ Shawn McDaniel. Shawn McDaniel was born with cerebral palsy which impedes him from being able to speak‚ move‚ or communicate with others‚ he has no control over his body. It pretty much does everything on his own‚ when it wants. Everyone thinks that he is unable to understand what is being said or what goes on.

world’s prescription drugs. A prescription drug is a medicine crafted by pharmaceutical companies that legally requires a medical prescription to be dispensed. In contrast‚ Illegal drugs are obtained unlawfully through undocumented transaction. Due to substance abuse these prescription and illicit drugs combined‚ kill tens of thousands of people each year. The three mainly abused types of prescription drugs are opioids‚ depressants‚ and stimulants. These 3 types all have something in common and that is

Many substances that we use on a daily basis are in fact part of a mixture. A scientist separated a mixture to obtain the specific substance that was in need. Many of the compounds and mixtures today are not found in its pure form‚ but in mixtures. Many scientists have the impression that separating mixtures is an important part of chemistry and modern academics. How can the components of mixture be separated and analyzed? Background Information: All elements and compounds are pure substances and

PRINCIPLES OF CHEMISTRY LAB I Experiment 2 Separation Of Mixtures INTRODUCTION A mixture can simply be defined as a substance that is made up or consists of two or more elements and/or compounds that are physically combined but that have not reacted chemically to form new substances. A mixture may be a solid‚ liquid‚ gas‚ or some combination of those states. Mixtures can be found almost every wher in our everyday lifes and some common examples are * sand and water * salt and water
