Acid And Base Ph Lab Report

Reacting Acids and Bases Lab Report Introduction Every liquid, except for distilled water, has either acidic or basic traits. An acid is sour tasting, and gives a sharp stinging pain in a cut or wound, and bases taste bitter, and feel slippery. A pH scale is used to determine what traits a liquid has; acidic or basic. The scale focuses on OH- (hydroxide ions) and H+ (hydrogen ions). The scale goes from 0 to 14. 7 is distilled water, as it is directly in the middle; neither acidic or basic. Acids are...

Lab Report Acid Base Titration

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 end point of the titration. The indicator used can change colors at different pH values. ...

Acids and Bases Mirza Hasan Mammadov Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids, they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition, although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not...

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids, as are carbonated beverages, tea, and battery acid. Common household bases include baking soda, ammonia, soap, and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis...

Studying the pH of Strong Acid, Weak Acid, Salt, and Buffer Solutions

Studying the pH of Strong Acid, Weak Acid, Salt, and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions, to determine the pH of various salt solutions, to prepare a buffer solution, and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6, 2.2, 2.9, and 3.8. The measured...

ka lab report

Titration of a Weak Acid Introduction: We will be using the LoggerPro and LabPro in order to help us determine our data. The purpose of this experiment is to follow the changes of pH during the titration of an acid and a base in order to determine the of the weak acid, . is a constant for a given acid at a given temperature. In this experiment we determined the Ka using two different methods: 1) the measurement of the pH of a solution containing a known concentration of a weak acid, and 2) measurement...

6-3: Concepts in Acid-Base Titrations

Acid-Base Titrations 6-3: Concepts in Acid-Base Titrations Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration, this is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) Titration curves (graphs of volume vs. pH) have characteristic shapes. The graph can be used...
