The spectrophotometer was developed around 1939 by a scientist named Arnold O. Beckman who was born in 1900 and passed away in 2004. Arnold Beckman was a chemist and inventor that also invented the pH meter that is used frequently by chemists and scientists in today's experiments....
What is a titrant in a titration? Titration: Titration is a conventional method for volumetric analysis where the concentration of the desired substance or sought for (analyte) is being determined. In this method, the graduated laboratory equipment called the burette is used to dispense a solution...
Solution 1 is called the titrant, and we say that it is used to titrate solution 2. ... For example, 25.00 mL of anitric acid solutionof unknown concentration might be added to a 250 mL Erlenmeyer flask. A solution of a substance that reacts with the solute in solution 2 is added t...
Industries that use titration chemistry include agriculture, biotech, chemicals, cosmetics, electronics, food and beverage, paints and pigments, paper and pulp, petrochemicals, and pharmaceuticals. For example, the titration is widely used in the food and beverage industry: dairy, edible oil, fat, ...
What are laboratory glassware used for? Beakers – One of the most common types of laboratory glassware, beakers are basic containers usedto hold samples and reagents. Burettes – Used to dispense liquid in exact quantities. Pipettes (Bulb and Graduated) – Used to move a small, measured amo...
Math: Math in math class is the similar, but not the same as math in a science class. The rules of math don't change, but the applications are different. Significant figures are used in science-based mathematical calculations. Answer and Explanation: ...
In the manufacturing process, Carbon Black particles are for- med that range from 10 nm to approximately 500 nm in size. These fuse into chain-like aggregates, which define the structure of individual Carbon Black grades. Carbon Black is used in a diverse group of materials in order to ...

The second common method is color-indicating titration, in which a pH indicator should be used, such as phenolphthalein. A burette is used to add the titrant to the sample where the permeant color change of the solution gives the endpoint of the solution, which indicates the total acid conten...
