What is the reading accuracy of a burette?
The reading accuracy of a burette is typically within 0.05 mL. This means that the burette can accurately measure the volume of a liquid to within 0.05 mL. This level of accuracy is important for precise titrations and other laboratory experiments where small volumes of liquid need to be measured. It is important to carefully read and record the volume on the burette to ensure accurate results.

What impact does leaving an alkaline solution in the burette for too long have on the accuracy of the measurement?
Leaving an alkaline solution in the burette for too long can lead to the formation of a white precipitate, which can affect the accuracy of the measurement. This precipitate can coat the walls of the burette and cause the solution to stick to the surface, leading to inaccurate volume readings. Additionally, the presence of the precipitate can also interfere with the reaction being measured, leading to inaccurate results. Therefore, it is important to properly clean and rinse the burette after use to prevent any potential inaccuracies in measurements.

Why can the formed iodine not react with tetrathionate and in iodometry, is the substance to be oxidized in my burette?
The formed iodine cannot react with tetrathionate because tetrathionate is a strong reducing agent and iodine is a mild oxidizing agent. In iodometry, the substance to be oxidized is placed in the burette because it allows for precise control over the amount of oxidizing agent added to the solution being analyzed. This ensures accurate determination of the substance being oxidized.

Why can the formed iodine not react with tetrathionate and why is the substance to be oxidized in my burette during iodometry?
The formed iodine cannot react with tetrathionate because tetrathionate is a stronger oxidizing agent than iodine. Tetrathionate will oxidize iodide ions to form iodine, but iodine cannot further react with tetrathionate. The substance to be oxidized is placed in the burette during iodometry because it needs to be slowly added to the iodine solution to ensure that all the iodine is reacted and the endpoint of the titration is accurately determined.

What are different forms of government in politics?
There are several different forms of government in politics, including democracy, monarchy, dictatorship, and oligarchy. In a democracy, power is held by the people, who elect representatives to make decisions on their behalf. Monarchy is a form of government in which a single ruler, such as a king or queen, holds power. A dictatorship is a form of government in which power is concentrated in the hands of a single leader, who often rules with absolute authority. Oligarchy is a form of government in which a small group of people hold power and make decisions for the rest of the population. Each form of government has its own advantages and disadvantages, and can have a significant impact on the lives of its citizens.

Who is responsible for legislation in residence law, the federal government or the state?
In the United States, legislation in residence law is primarily the responsibility of the state government. Each state has its own laws and regulations governing residency requirements, landlord-tenant relationships, and property rights. While the federal government may enact laws that impact residence law, such as fair housing regulations, the majority of legislation in this area is determined at the state level.
