What are some examples of chemical indicators?

Litmus tests for acidity are probably the most well-known, but there are lots and lots of them. The Encyclopaedia Britannica article below is pretty thorough.\n\nGood luck.

If you are looking for properties of some specific chemical then search for MSDS (Material Safety Dada Sheet) for that particular chemical in Google or Yahoo search engines.\nHere, I am giving you a list of websites which can give you general information on symbols. There will be slight variation in the depth of descriptive material depending on site to site.\nYou can copy and paste following links in your browser's address line:\n(1) www.geocities.com/david_charles_curran/safety\n(2) http://en.wikipedia.org/wiki/Hazard_symbol\n(3) http://www.hse.gov.uk/chip/phrases.htm\n(4) http://www.chem.utoronto.ca/healthsafety/guide/symbols.htm

The position of the elements in the periodic table gives you clues about the valences of each element. Also, if you remember the formulae for familiar substances (like carbon dioxide, water, sulfur dioxide, hydrochloric acid, etc) that will also give you clues about possible or likely valences. \n\nThe final answer is:\n\nmemorize.

Any acid, for example:\n\nHCl + H2O  --> Cl- + H3O+

A chemical property is a property of a substance that becomes apparent during a chemical reaction, and can only be observed by changing the substance's chemical identity.

The sign there is a chemical reaction is the fact there is heat being released.  Evidently, the reactant have more energy, because they are able to release that energy in the form of heat.

The "point" of titration.\nAt a specific point: the chemical being titrated will reach the designated color.  The indicator will show how much was titrated at the point of color change.

There are many types of pH indicators which will change color withint a certain range of pH values.  Many of these indicators might be dificult for the "common person" to get a hold of though.\n\nUsing Litmus paper is an easy way to test the pH of a substance.\nBased on the color change of the Litmus paper, a general idea of the pH can be determined.\n\nOne can also use other, natural, indicators.\nFor example, red cabbage contains a natural pH indicator which can be extracted by boiling (this will STINK up your whole house, best to do it outside of possible).\nhttp://chemistry.about.com/library/weekly/aa012803a.htm\n\nYou can also get pH probles whcih work by placing an electrode into the solution to be measured and getting a reading off of the either digital display or, in the case of cheaper probles, the value the needle points to on the meter.  Some of the "good qualitity" probles can be a little expensive, but a cheap substitute is a soil pH meter.  Although soil pH metes are really not designed to be used to measure a solution's pH and only have a limited range, it can work well for many applications.\n\nIf you want to get a numeric value for the pH,\nMy advice is to go with the soil pH meter if you dont plan on measuring anything which will have pH values below roughly 3 or 4 and nothing higher than about 8 or 9.  If you do plan to, you might want to go with a "real" pH meter.\n\nIf you just want a general range of the pH (whether something is just acidic or alkiline), then go with Litmus paper or some other form of cheap indicator (cabbage juice).
