Practical 3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many plains and craters. The largest crater on Mercury is the Caloris Basin with a diameter of 1550km. Venus‚ the second planet from the Sun‚ is a solid and rocky terrestrial

Analysis Paper: Fluid Volume Deficit “Fluid volume is a term that describes the balancing of input and output of fluid in the body” (Welch 2010). This balance can be affected by many factors: inadequate intake‚ shock‚ vomiting‚ diarrhea‚ or too much output. It can also be caused by third spacing. Fluid volume balance is very important to monitor patients because it can affect every body system and can easily be altered. Fluid volume deficit is more commonly referred to as dehydration.

Scheduled Areas and Tribal Areas : Scheduled Tribes live in contiguous areas unlike other communities. It is‚ therefore‚ much simpler to have an area-approach for development activities and also regulatory provisions to protect their interests. In order to protect the interests of Scheduled Tribes with regard to land alienation and other social factors‚ provisions of ‘‘Fifth Schedule" and ‘‘Sixth Schedule"have been enshrined in the Constitution. The Fifth Schedule under Article 244(1) of Constitution

This was done by determining the volume of a single drop of using a graduated cylinder to measure a known amount of consistent drops‚ which allows for the individual volume to be determined mathematically. MATERIALS AND METHODS: Pipette‚ 10ml graduated cylinder‚ water‚ rubbing alcohol and hand soap. A pipette was used to place

1. Explain the terms area of convergence and area of origin and explain what each term reveals to an investigator. The area of convergence of an impact spatter pattern is the area the individual stains emanated from on a two-dimensional plane. The area of origin of a bloodstain pattern in three-dimensional space may represent the position of the victim or suspect when the stain-producing event took place. These areas can determine and reveal to an investigator the direction of force‚ angle of impact

When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing
