Two examples of olfactory indicators are Onion and vanilla extracts. When either of the two are mixed with a solution containing an acid, the smell of the indicator does not change. Whereas, when mixed with a solution containing a base, the smell of the indicator fades away and cannot beRead More →
The term “iodometry” describes the type of titration that uses a standardised sodium thiosulfate solution as the titrant, one of the few stable reducing agents where oxidisation of air is concerned. Why KI is used in iodometry? KI, or potassium iodide, is used in iodometric titration because the iodide willRead More →
Potassium Permanganate is a flexible and potent oxidant which can be used by overt or indirect titration to classify many compounds. A special value of Potassium Permanganate is that it acts as an indicator of its own. What does self indicating mean? Self indicating or self indicator is the substanceRead More →
What is an overflow indicator in 2’s complement addition? Overflow Rule for addition If 2 Two’s Complement numbers are added, and they both have the same sign (both positive or both negative), then overflow occurs if and only if the result has the opposite sign. Overflow never occurs when addingRead More →
Liquefied gases, such as liquid nitrogen and liquid helium, are used in many cryogenic applications. Liquid nitrogen is the most commonly used element in cryogenics and is legally purchasable around the world. Liquid helium is also commonly used and allows for the lowest attainable temperatures to be reached. What processesRead More →
This probably isn’t the answer you want to hear, but you can be varying degrees of dilated or effaced for several days — or even weeks — before true labor begins. Alternatively, you might not be dilated or effaced at all and still go into labor within hours. First-time momsRead More →
Some human traits, like bipedalism, evolved very early, while others, like large brains, did not evolve until relatively recently. Still other traits, like molar size, evolved in one direction only to be pushed back later by changing ecological pressures. What features did you use to identify which skull was humanRead More →
Use. Murexide is used in analytical chemistry as a complexometric indicator for complexometric titrations, most often of calcium ions, but also for Cu, Ni, Co, Th and rare-earth metals. It functions as a tridentate ligand. Why is murexide a good indicator? The indicator used is murexide which is a differentRead More →
Fair Weather Cumulus Clouds: puffy cotton balls floating in the sky. Fair weather cumulus have the appearance of floating cotton and have a lifetime of 5-40 minutes. Why do clouds look fluffy? When warm air rises from the ground, it carries water vapor with it. When the water vapor meetsRead More →
