Acids vs Bases In chemistry‚ when some elements are mixed‚ the compounds that are formed can be classified depending on its characteristics‚ just like acids and bases. Acids are defined as compounds that donate a hydrogen ion‚ H+‚ to another compound. Bases are the chemical opposite of acids. They both are different in many ways. One way in which acids and bases differ is the pH and the pOH. The pH is a number used to denote the hydrogen-ion concentration‚ or the acidity‚ of a solution. In the

Strategic Analysis: Adrenaline Air Sports Adrenaline Air Sports is a sky diving company that started only a few years ago. While it is dealing with internal and external factors that are restraining it from its greatest potential‚ Adrenaline Air Sports must navigate through its problems and outweigh its competitors. Sky diving is a sport that must be done in an area away from normal population. Adrenaline Air Sports is located in Jonesville‚ North Carolina‚ a small resort town that gets about

I think that people who participate in extreme sports do it for the “ adrenaline rush”. Because “life would be boring if we don’t try new things “ that’s what people say‚ but in reality they’re just putting themselves in risk without thinking the consequences .They are a lot of new things you can try without putting yourself and life in risk‚for example you can dance‚travel ‚ or practice some other sports where you don’t need to risk your life. Try them even if you don’t know how to play them and

EXPERIMENT 3: INTRODUCTION TO TITRATION – DETERMINATION OF THE MOLARITY AND CONCENTRATION OF SULPHURIC ACID BY TITRATION WITH A STANDARD SOLUTION OF SODIUM HYDROXIDE INTRODUCTION Reaction of acid and base is one of the most common reaction in chemistry. This reaction is also widely known as neutralization. In this experiment‚ we used titration technique which involves accurately measuring the volume of a solution required to react with another reagent. An indicator must be used to determine the

Extreme Sports: Are They Worth The Risk? Broken bones‚ head trauma‚ shark attacks‚ and casualties all while playing the sport you love. Is it worth it? With extreme sports come extreme risks. There are many controversies over these sports as to whether they are ethical or not and why anybody with the right mindset would consider participating in such events. These sports often involve high speed‚ great heights‚ a high level of physical exertion‚ and highly specialized gear or spectacular stunts

A specific example of such is in the body‚ acids and bases have to be balanced in order to provide the optimal pH in the system for normal physiological processes. Anything digested by the body has

figure out which one it is based on properties‚ along with the pH. Acids taste sour‚ and bases taste bitter. Using the pH scale‚ you are able to know how strong of an acid or base a liquid is. High concentration of [H+] ions means that the liquid has a low pH. Therefore a liquid with a low concentration of [H+] would have a high pH. A pH of less than 7 represents an acid‚ while a pH above 7 represents a base. A pH of 7 would be neutral. In this lab‚ we used red cabbage juice as a pH indicator to

BASE ISOLATED BUILDINGS What is base isolation? When a building is built away (isolated) from the ground‚ resting on flexible bearings or pads known as base isolators. It is of the most popular means of protecting a structure against earthquake forces. HISTORY The first evidence of architects using the principle of base isolation for earthquake protection was discovered in Pasargadae. One of the world’s first base-isolated structures – the William Clayton building Base Isolation
