NH3, HF, PH 3, CH 4, H 2 S c) metal hydrides prelznih second OXIDES a) acidic oxides - usually meta

First HYDRIDES - compounds with hydrogen (H). a) metal hydrides - oxidation number of hydrogen is -1
NH3, HF, PH 3, CH 4, H 2 S c) metal hydrides prelznih second OXIDES a) acidic oxides - usually metal oxides - with water grade acids, ie are acid anhydrides.
acid anhydride wonderful SO 2 + H 2 O ---> H 2 SO 3 b) basic oxide - metal oxides pronounced - make with water base - ionic compounds
Anhydride base Na 2 O + H 2 O ---> 2NaOH c) amphoteric oxides - reguju with acids and bases
3rd Peroxide - build them metals Ia and IIa group - react with water and extract hydrogen peroxide (H 2 O 2) - oxidation number of oxygen wonderful is -1
4th ACID - are those substances that can provide protons (proton donor) a) monobasic - HC l, H NO 3 b) višebazne - H 2 SO 4, H 3 PO 4 c) of oxygen - HN O 3 d) bezkiseonične wonderful - HCl (no anhydride) - acids are divided into strong, weak and moderate. - Dissociation of acid flowing slowly wonderful in višebaznih strong acid, the first step is irreversible, and the other is reversible:
Fifth BASE - compounds that are in som composition containing one or more hydroxyl groups linked to the metal. a) monokisele - The OH KOH b) višekisele - Ca (OH) 2, Fe (OH) 3 - divided wonderful into low, moderate and severe, and the normal (NaOH (OH) 3) and amphoteric wonderful (Pb (OH ) 2, Al (OH) 3). 6th SALT - the influence of acid to base or vice versa comes to the neutralization reaction in which the resulting salt and water. Incorporating a metal salt formed from the base and the acid residue of the acid. This reaction is exothermic. wonderful
