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
=======
Potassium hydrosulfide is the inorganic compound  with the formula KHS.  This colourless salt consists of the cation K+ and the bisulfide anion [SH]−.  It is the product of the half-neutralization of hydrogen sulfide with potassium hydroxide. The compound is used in the synthesis of some organosulfur compounds.  It is prepared by neutralizing aqueous KOH with H2S.  Aqueous solutions of potassium sulfide consist of a mixture of potassium hydrosulfide and potassium hydroxide.
The structure of the potassium hydrosulfide resembles that for potassium chloride. Their structure is however complicated by the non-spherical symmetry of the SH− anions, but these tumble rapidly in the solid high temperatures.Addition of sulfur gives dipotassium pentasulfide.
