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

Analytical Response 9/29/11 Power of Communication Technology After reading the paper written by Mark Carty‚ on “Communication Technology in Social Movements” it all seemed to make sense. Power really is a violent relationship with almost everything‚ if not everything. The paper exemplified how the power of communication technology is violent and extremely dominant over higher authority. Cell phones took over the Internet and landlines in terms of communication‚ and that’s when the text message/SMS

Almost all food commodity has its own political and gendered history

see all the variations in components of loading techniques that affect the bullet’s point of impact. Here are some ways to expand the consistency and accuracy in ammunition for long range shooting. Powders & Primers Propellants will also require testing to find the best results. Long range shooting demands the variation stay as low as possible‚ so keep in mind that finer-grained powders will typically meter the easiest. Weighing each charge by hand is a great habit to ensure consistency. Consistency

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

ACID / BASE BUFFER SYSTEMS Abstract A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solutions (Bicarbonate/carbonic acid)‚ Lake water and distilled water were obtained to compare their buffering behaviours when mixed both with an acid and a base. The results showed buffering capacities for

Peria‚ Ellen Faith L. Tacula‚ Jassy Camille D.S. Activity 11 Acids and Bases I. Objectives * To identify some acids and some bases which are used in common household products. * To construct an operational definition of an acid and a base‚ using the characteristic properties of those substances. II. Procedure A. For acids * Place 2ml each of dilute acetic acid‚ hydrochloric acid‚ sulfuric acid‚ carbonated drink (colorless) and calamansi

For my project‚ I had to create my own acid-base indicator and find out what happens when it is placed in an acidic solution (vinegar) and a basic solution (dissolved baking soda). I chose my indicator to be a fruit because fruits can be very effective at determining how acidic or basic a substance is. My fruit was a blueberry‚ but I couldn’t use raw blueberries because it’s not going to give me the best results. I had to make blueberry juice. I did this by placing several blueberries in a blender

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
