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

Bimetallism refers to a monetary standard or system based upon the use of two metals‚ traditionally gold and silver‚ rather than one (monometallism). This paper focuses on the factors which led to the decline of bimetallism as an international monetary standard. In the late 19th Century‚ bimetallism was replaced with monometallism as countries began to peg their currency to one metal‚ either gold or silver. Many reasons contributed to this. Bimetallism follows the Gresham’s Law. (Gresham’s law-When a government

The Chinese Empire experienced numerous political‚ economical‚ religious‚ and cultural transformations between 1400 and 1750 CE. The Qing empire‚ an empire built within the Chinese empire consisted of non-chinese people. Qing Empire took over Eurasia which was ruled separately from China; and the officials had no intentions to incorporate Chinese culture into the locals in Eurasia as a sign of respect for the different cultures residing there. For example‚ Qing rulers forbid Chinese merchants from

of solid copper metal‚ in the form of a wire‚ with aqueous silver nitrate. Before we began the lab‚ we hypothesized that when silver nitrate‚ AgNO3‚ reacts with copper‚ Cu‚ the oxidation number of silver (Ag) ions that form will be +1. The unbalanced chemical equation that we used to represent this reaction is Cu + AgNO3 → Ag + Cu(NO3)2. In order to find the approximate masses of reactants needed to produce about 2 grams of silver‚ we found the molar masses of each of the reactants and products:

non-fiction book written by Nate Silver that talks about predictions based on probability; particularly focusing on the outcomes of real-world predictions and why they did or did not fail. Published in 2012‚ this book is a commentary on the world of probability made by an ex-statistician. Silver begins this work by effectively emphasizing the relevance of his points by supporting his argument with data applicable to a wide audience. In the introduction‚ Silver begins by talking about the

King Hiero later found out that the crown may not have been of pure gold‚ but made of a gold and silver mix. Hiero called in a young man by the name of Archimedes because he was capable of revealing the truth. How did Archimedes use his principle to solve King Hiero’s problem? One day‚ while Archimedes was getting into the bath tub‚ he noticed

This process resulted in a surfeit of waste and was expensive due to laborintensive processing of the nal device. By contrast‚ conductive inks are now available that use existing printing technologies such as screen‚ gravure‚ exographic‚ offset‚ and inkjet to print conductive traces directly onto rigid and exible substrates relatively
