Chem- Acids, Bases and Salts Flashcards
what is an acid?
An acid is a substance that when dissolved in water, it ionizes and releases hydrogen ions.
Why is an acid a proton donor?
ANS.
What is an acid anhydride?
An acid anydride is a compound that reacts with water to form an acid
What are some examples of acid anhydrides?
Carbon dioxide, sulphur dioxide, nitrogen dioxide.
BLANKS are acidic oxides.
Acid anhydrides
Name SIX properties of an acid
pH less than 7
corrosive
conductivity
sour taste
turn blue litmus red
give off h+ ions
Name the 4 oxides
Acidic, Basic, Amphoteric and Nuetral
Describe acidic oxides and give 4 examples
Acidic oxides are oxides of some non metals that react with alkalis to form a salt and water
They can also react with water to form an acid hence why an acid anhydride is an acidic oxide
Examples include: Carbon dioxide, nitrogen oxide and sulphur oxide, sulphur trioxide
What is an alkali?
An alkali is a base that dissolves in water to produc OH- ions
what are basic oxides?
Give examples
Basic oxides are oxides of metals that reast with acids to form a salt and water.
Magnesium oxide, Iron(III) oxide, Copper(II) oxide
what are amphoteric oxides?
Give examples
amphoteric oxides are some metals that react with both acids and strong alkalis to produce a salt and water.
Lead(II)oxide, aluminum oxide, zinc oxide
What is the formula for basic oxides?
basic oxide + acid ARROW salt and water
Whats the formula for acidic oxides?
alkali + acidic oxide ARROW salt and water
what are neutral oxides?
nuetral oxides are oxides of some non metals do not react with either acids or alkalis
carbon monoxide, nitrogen monoxide, dinitrogen monoxide
what determines the strength of an acid or alkali?
Its degree of ionization
