Acids, Bases and Salts The nature of the solution can be either a base or a neutral solution. Acidic solutions change blue litmus red, hence it is not acidic. Bases change red litmus to blue hence there is no change in the colour of blue litmus paper. Neutral solutions haveRead More →
The greater the solubility of a solute, the greater the boiling point. What factors affect boiling point? The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling willRead More →
The common units for fugacity calculations are mol m−3, which are air concentration units. This necessitates unit conversions for the fleeing between other “nonair” compartments. What is fugacity in thermodynamics? Fugacity – Wikipedia. In chemical thermodynamics, the fugacity of a real gas is an effective partial pressure which replaces theRead More →
Paula’s Choice 2% BHA Power Liquid Exfoliant. Cosrx Blackhead Power Liquid. The Ordinary AHA BHA Peeling Solution. Why is the ordinary peeling solution banned in Australia? The Ordinary AHA 30% + BHA 2% Peeling Solution is not available in Canada, Korea, New Zealand, and Australia because it is qualified asRead More →
Air is an example of a solution as well: a homogeneous mixture of gaseous nitrogen solvent, in which oxygen and smaller amounts of other gaseous solutes are dissolved. Is oxygen and air a solution? For example, one can make a solution of two gases. In fact, the air around usRead More →
Isotonic IV Fluids 0.9% NaCl (Normal Saline Solution, NSS) Dextrose 5% in Water (D5W) Lactated Ringer’s 5% Dextrose in Water (D5LRS) Ringer’s Solution. Nursing Considerations for Isotonic Solutions. 0.45% Sodium Chloride (0.45% NaCl) 0.33% Sodium Chloride (0.33% NaCl) 0.225% Sodium Chloride (0.225% NaCl) What are some examples of isotonic hypertonicRead More →
Check: Review the test, analyze the results, and identify what you’ve learned. Act: Take action based on what you learned in the study step. If the change did not work, go through the cycle again with a different plan. If you were successful, incorporate what you learned from the testRead More →
A standard solution is a a solution of accurately known concentration prepared from a primary standard (a compound which is stable, of high purity, highly soluble in water and of a high molar mass to allow for accurate weighing) that is weighed accurately and made up to a fixed volume.Read More →
Mohr method The solution needs to be near neutral, because silver hydroxide forms at high pH, while the chromate forms H2CrO4 at low pH, reducing the concentration of chromate ions, and delaying the formation of the precipitate. Which type of acid is used in Mohr method? of potassium chromate solutionRead More →
Aqueous carbonic acid (H2CO3) decomposes into a carbon dioxide gas and liquid water. What state is carbonic acid? Carbonic acid is often described as a respiratory acid since it is the only acid that is exhaled in the gaseous state by the human lungs. It is a weak acid andRead More →
