What is Humidity?The simple meaning of humidity is ‘atmospheric moisture’ or ‘amount of water vapor in the atmosphere’.Humidity is the amount of water vapors present in the atmosphere (or air). Water vapors are the gaseous state of water and are invisible.Humidity can be measured by three ways that are: absolute, relative and specific.    1.Absolute humidity is the water content of air in the gram per cubic meter at a given temperature.     2.Relative humidity is expressed in percentage, and it measures the current absolute humidity relative to the maximum humidity for that temperature.    3.Specific humidity is expressed as the ratio of the mass of the water vapors to the total mass of moist air parcel.What is Absolute Humidity?To understand absolute humidity let’s assume you are standing in ground and you collect some air. Now you check that air volume in your chemistry lab and get accurate amount of water vapors in gram. If you collect 1 cubic meter of air volume and it contains 30…

Analytical Balance

Analytical BalanceWhat is an analytical balance? Analytical balance is a lab-instrument used to determine mass of any matter very precisely. These analytical balances are very sensitive and expensive lab-instruments, and also upon the accuracy and precision of analytical balance the accuracy of lab-analysis result depends so handle these balances very carefully. Generally used analytical balances are balances with the capacity of 100 gram to 200 gram and the sensitivity of 0.1 milligram to 0.001 milligram. For any quantitative chemical analysis there is need of analytical balance for the weighing of sample for analysis and weighing of reagents for solution preparation. Analytical balance pan used to put sample on it is enclosed in a glass-fitted case, means analytical balance sensitivity requires that it to be protected by the draft shield or enclosure.
Definition of Analytical BalanceAnalytical balance is a lab instrument with a scale to measure the mass to a high degree of precision.…

Catalytic Decomposition of Hydrogen Peroxide H2O2 – Elephant’s Toothpaste Experiment

Catalytic Decomposition of H2O2 – Elephant’s Toothpaste ExperimentElephant's toothpaste is a foamy substance formed as a result of rapid decomposition of hydrogen peroxide. Elephant’s toothpaste reaction experiment is generally used for classroom demonstrations as it requires fewer ingredients and makes a "volcano of foam".
Description:H2O2 is decomposed by Iodide Ion. Iodide ion is used as a catalyst and these iodide ions come from KI (Potassium Iodide) or NaI (Sodium Iodide). This decomposition reaction liberates water, oxygen and heat. Materials: 30% H2O2 (Hydrogen Peroxide)1 Liter Graduated cylinder KI (Potassium Iodide) or NaI (Sodium Iodide). Food Color for funLiquid Dish DetergentProcedure: 1.Pour 50 mL of 30% H2O2 (Hydrogen Peroxide) in 1 L graduated cylinder. 2.Then, add 3-4 drops of food color in 1 L graduated cylinder to make colored H2O2 solution. 3.Then, start adding liquid dish detergent or soap from the side of 1 L graduated cylinder to make a small layer o…
