  • Creating Malachite egg

    One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

  • Diamonds Are Forever

    Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?

  • Chemical Safety

    People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

  • Interesting facts about metals

Canal Ray

Stream of positively charged particles (cations) that moves toward the negative electrode in cathode ray tubes, observed to pass through canals in the negative electrode.

Fluorescence

Absorption of high energy radiation by a substance and subsequent emission of visible light.

Extrapolate

To estimate the value of a result outside the range of a series of known values. Technique used in standard additions calibration procedure.

Reaction Quotient

The mass action expression under any set of conditions (not necessarily equlibrium), its magnitude relative to K determines the direction in which the reaction must occur to establish equilibrium.

Anode

In a cathode ray tube, the positive electrode. Electrode at which oxidation occurs.

xanthene dye

Any of a group of dyes having a molecular structure related to that of xanthene in which the aromatic (C6H4) groups are the chromophore.

 

Two chemistry egg tricks

The French have a saying: "You cannot cook an omelet without breaking eggs."Chemists hearing this proverb totally disagree. There is nothing easier than cleaning an egg without breaking its shell.
Probably our readers have already guessed how to do this, as it’s known that the hard shell of the egg is carbon dioxide, like chalk and marble.

Exothermicity

The release of heat by a system as a process occurs.
