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)

The virtual manipulative that I ended up exploring was base blocks. The main goal of this virtual manipulative was to show students a number and have them express it through the base blocks. This manipulative ending up working better in some regards when compared to a concrete manipulative. One reason that it worked better is that it automatically checks your answer once the student has made it to the number presented‚ which cannot be done by concrete manipulatives. Another reason that it works better

ACIDS & BASES Acids/Bases Basics Acids and bases are common solutions that exist everywhere. Almost every liquid that we encounter in our daily lives consists of acidic and basic properties‚ with the exception of water. They have completely different properties and are able to neutralize to form H2O‚ which will be discussed later in a subsection. The table below compares the different properties between them: pH Scale Since acids increase the amount of H+ ions present and bases increase

The plaintiff‚ Margaret Hollar was not employed at the time of the accident in question. The plaintiff had a history of having an L4-S1 discectomy and laminectomy. Ms. Hollar testified that she had a history of severe headaches‚ which began when she was 20 years of age. The plaintiff was involved in an accident in 2001 in which she slipped on ice and injured her neck and back. That injury led to her back surgery‚ as a result of her chronic back pain she was unable to return to work. The plaintiff

Margaret Visser writes about fasting in her short story “Running on Empty”. Visser effectively presents her writing style as expository and her thought process as deductive with denotative diction through the use of objective writing only to persuade the reader to her way of thinking. Visser’s writing is in fact persuasive‚ connotative and inductive. After a careful analysis of the story‚ one must conclude that Visser intentionally attempts to convince her audience that fasting is wrong by appealing

Chemistry A Rap 1 4/6/12 Acid and Base Report If someone were to ask the common teenager in the US‚ “What’s acid?” they would probably respond with something akin to “It’s that one drug that makes you see stuff that isn’t really there and just kinda makes you crazy”. And if that same someone was to ask that same teenager‚ “What’s a base?” their response would most likely have something to do with either baseball‚ or freeze-tag. The thing is‚ most people don’t really understand the most common
