Why Is Calcium Chloride Powder Used Extensively As A Bleaching Agent? In simple terms‚ calcium chloride is an inorganic compound having chemical formula CaCl2 (H2O)x where x can be 0‚1‚2‚4 and 6. All the salts produced by calcium chloride powder has a unique characteristic that they are highly soluble in water. This helps in applications where you need to remove snow‚ ice‚ or frost from any surface or even simple dust removal. It can absorb moisture from the surrounding environment‚ which is also

Lithium Carbonate and Bipolar Disorder Lithium is a naturally occurring element that is refined to treat certain psychiatric disorders like bipolar disorder. Lithium is a naturally formed element‚ and can be found in many foods. The element has various forms such as lithium carbonate‚ lithium orotate‚ and lithium aspartate (“The Science and Practice”). The differences in lithium lie within the effects of salt on molecular weight‚ and the percentage of lithium. Lithium carbonate specifically is used

the concept of the flux capacitor. Before Doc can make his first trip‚ Libyan terrorists‚ from whom he stole the plutonium‚ arrive and shoot him. Marty attempts to escape using the machine and inadvertently activates the time machine where he travels back to 1955 and finds himself without the plutonium needed for the return trip. While exploring the 1955 Hill Valley‚ Marty meets the teenage George who is being bullied by Biff Tannen. As George is about to be hit by Lorraine’s father’s car‚ Marty pushes

titrate a weak acid with a strong base. In a titration of a weak acid with a strong base the titrant is the strong base and the analyte is a weak acid. The reaction that will occur is the direct transfer of protons from the weak acid to the hydroxide ion. The data gathered will be represented on the titration curve‚ a graph of the volume of titrant being the strong base plotted against the pH .The pH is an indicator of an acids strength. The titration curve can be used to determine the pKa. By reading

Porter’s model highly focuses on rivalry and profitability but has some major limitations that have many organizations consistently reevaluating their strategic plans. Porter indirectly rebutted the assertions of other forces‚ by referring to innovation‚ government‚ and complementary products and services as "factors" that affect the five forces (Porter‚ 2008). He assumed that his model will allow markets to stay fairly stable‚ not taking into account brisk technological advances or increasing competition

What is power? Power is having strength and being forceful‚ physically applying your strength to another individual. In order to become powerful‚ steps are always considered‚ you aren’t powerful with a blink of an eye‚ you have to start from scratch‚ being powerless. One of the fundamental expectations underlying this premise is the capacity or ability to direct or influence behaviour of others or the course of events. Power can be gained or lost.

Silver Nitrate Titration Introduction This experiment was conducted to work out the concentration of the chloride ions in the school swimming pool water and to see if it fits in the required range of concentration of chloride ions in the swimming pool water. This was done by titrating a small sample of the school swimming pool water with silver nitrate‚ which would form a white precipitate of silver chloride. The equation of this process is: The end point of the titration (when all of

Short Narrative Essay Tradition has always been something that my mother and grandmother thought very highly of. Of all the family traditions that families have getting up on Sunday morning having breakfast and being in Sunday school and church on time was a must. We were going to be in Sunday school and church on time even if we didn’t finish eating breakfast and you had better not get in church and say something about being hungry when you had time to eat your breakfast

Potentiometric Titrations Accuracy The accuracy of a potentiometric analysis is limited by the measurement error for the cell’s potential. Several factors contribute to this measurement error‚ including the contribution to the potential from interfering ions‚ the finite current drawn through the cell while measuring the potential‚ differences in the analyte’s activity coefficient in the sample and standard solutions‚ and liquid junction potentials. Errors in accuracy due to interfering ions

Experiment 2 Acid/Base Titration John J. Purdue CHM 321 – Fall 2012 TA: Scott Cole Section 1 September 4‚ 2012 Unknown Concentration: X.XX ± X.XX M (@95% confidence interval) (adapted from a report prepared by N. Skrynnikov‚ 2009) Abstract The concentration of an unknown acid (HA) solution was determined by titration with a standardized solution of sodium hydroxide. The standardization of NaOH was done by titration with a solid acid sample‚ potassium hydrogen phthalate (KHP)‚ and phenolphthalein
