Listening is a more natural way of learning, when compared to reading. Written
language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through
audio (audio article). You could even learn subconsciously by playing the audio
while you are sleeping! If you are planning to listen a lot, you could try using
a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Tripotassium phosphate, also called potassium phosphate tribasic, is a water-soluble ionic salt which has the chemical formula K3PO4. It has a molecular weight of 212.27 g/mol in its anhydrous form. The compound is slightly hygroscopic. However, it has a very high melting point of 1380 °C which allows it to be heated to remove water without decomposing the salt. Tripotassium phosphate is a strong inorganic base and has been used as a catalyst for many reactions. It is a tribasic salt which can be used as a food additive or to form buffer solutions in water. Besides its use as a catalyst, it has also been used for its antimicrobial properties. It is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent. In combination with fatty acids, it is a potential antimicrobial agent in poultry processing. It is relatively inexpensive compound compared to other chlorine compounds like calcium hypochlorite (Ca(OCl)2) and sodium hypochlorite solution (NaOCl) which are used for killing bacteria in water. As a fertilizer, its proportions of N, P2O5, and K2O are 0-33-67.
