My favourite book is "Robinson Crusoe" by Daniel Defoe. D. Defoe (1660—1731) was a great master of realistic detail. The novel "Robinson Crusoe" was written in 1719. The novel is praise to human labour and the triumph of man over nature.Defoe shows the development of his hero. At the beginning of the story we see an inexperienced youth, a rather frivolous boy, who then becomes a strong-willed man.Robinson Crusoe's most characteristic trait is his optimism. His guiding principle in life become "never say die" and "in trouble to be troubled is to have your troubles doubled".He had confidence in himself and in man. He believed it was within the power of man to overcome all difficulties. Crusoe was an enthusiastic worker and always hoped for the best.Defoe is a writer of the Enlightenment. He teaches people how to live, he tries to teach what's good and what's bad. His novel "Robinson Crusoe" is not only a work of fiction, an account of adventures, a biography and an educational pamphlet.<span>It is a study of man, a great work showing man in relation to nature and civilization as well as in relation to labour and private property. </span>

Buffer solutions, depending on their composition, are divided into 2 main types:
acidic and basic.
Acid buffering systems are usually formed by a weak inorganic or
organic acid and a salt of the same acid with a strong base.
For example:
1) CH3COOH + CH3COONa - acetate buffer
weak acid salt acid
2) H2CO3 (H2O + CO2) + NaHCO3 - hydrocarbonate or
weak acid salt acid bicarbonate buffer.
Basic buffer systems are formed by weak inorganic or
organic base and a salt of this base with a strong acid. For example:
1) NH3 · H2O (NH4OH) + NH4Cl - ammonia buffer
weak base salt
2) C2H5 – NH2 + C2H5NH3Cl - ethylamine buffer
weak base salt
Basic buffer systems are formed by weak inorganic or
organic base and a salt of this base with a strong acid. For example:
1) NH3 · H2O (NH4OH) + NH4Cl - ammonia buffer
weak base salt
2) C2H5 – NH2 + C2H5NH3Cl - ethylamine buffer
weak base salt.
