KHP (potassium hydrogen phthalate) is available extremely pure (which is always good for a primary standard) and gives a very sharp end-point especially with Crystal Violet Indicator
im not totlay sure if it's deinately dangerous but when at room temperature its quite dangerous to breathe in. i think this is corredt. hope this helped you!
Anything over 10ppm is not good
Very dangerous I would presume as bases are used as drain cleaners. So, there must be a very good reason not to use a strong acid such as sulfuric acid.
Mercury is a chemical element, and the nature and behavior of chemical elements cannot accurately be described as good or bad. An important aspect of the behavior of mercury is that it is liquid at room temperature.
Can't think of anything specific, but surfactants would be a good place to look: soaps, detergents, etc.
We will classify this new species as a mammal.How do you classify this, Mister Burns?
You find things easier
Lynx, Styx ,Spry Phthalate, Physics, Psychology, etc Lynx, Spry, Physics, and Psychology don't have four consonants together. The "y" in each one is a vowel, as it is in Styx, which isn't a word, but a proper name. Phthalate is good, but a simpler word with four consecutive consonants is "worldly."
It depends
It's not always dangerous. If you are being a good person to a very dangerous person who doesn't consider it then...
Because Adolf Hitler, according to record, whilst trying to make the atomic bomb, got his finger stuck in himmlers anus. as he removed it, liquid s**T came out in a "spray" form. This was very funny to the other Nazi babies. So Adolf got some potassium hydrogen phthalate and burned the C**ts. Then Adolf said to Himmler "f**k me that's a good primary standard batt!"
Streak is one good way to start identifying a mineral, but poor for classification.
If income elasticity is positive, then it is a normal good. Otherwise, it is an inferior good.
Chemical property. :D good luck!
Some good topics to classify could be foods or animals. Classifying people is a good idea too. Try to classify something that you are interested in, and try to think of something creative as well.
