inorganic compounds Flashcards
name the inorganic compounds?
- oxides
- peroxide
- hydroxides
- hydracids
- nitrates
- phosphates
- Sulfates
what are the compounds of oxide and the charge?
aluminium oxide- ceramic materials
zinc oxide- used as a bulking agent
-2
what are compounds of peroxide and the charge?
sodium peroxide- a bleaching agent
hydrogen peroxide- antiseptic
-1
what are compounds of hydroxides and the charge?
iron hydroxide- an agent for the removal of toxic selenate from water
aluminium hydroxide- relieve heartburn
-1
what are the compounds of phosphates and the charge?
polyphosphates- synthesises energy and phosphate storage
pyrophosphates- in cleaning compounds
-3
what are the compounds of Sulfates and the charge?
magnesium sulfate- control blood levels of magnesium
copper sulfate- in plan killers
+4
what is a metal ion?
a metal ion is a type of atom compound that has an electric charge.
many metal ions s are cofactors of enzymes
what are oxides?
co2 is a covalent bond. animals produce carbon dioxide in respiration and plants use it to produce sugars in photosynthesis
nitrogen oxides are also covalent, are important biologically because of their environmental impact. nitric oxide is important in the human body
what are peroxides?
peroxides are produced during amino acid metabolism and must be degraded in the liver
powerful oxidising agent because it reduces the oxidation state from -2 to -1
hydrogen peroxide is used by cells in the immune system to kill other cells in the body that are infected with a virus
what are hydroxides?
have inorganic bases
used in titration to calculate the concentration of an unknown acid
what are hydracids?
all sources of H+ ions hydrofluoric acid (HF) is a highly corrosive and highly toxic due to the fluoride ions produced
hydrogen sulfide (H2S) is a highly toxic gas as it prevents mitochondria from carrying out respiration into amino acids and nucleic acids oxidation state of +1
what are nitrates?
contain N03- ions
silver nitrate is used to test for halides
in plants, nitrates are converted into ammonium ions and incorporated into amino acids and nucleic acids
oxidation state of -2
what are phosphates?
phosphates form an essential part of DNA and phospholipids
it is a key component of ATP and is used to form cell membranes
oxidation state of -3
what are sulphates?
found in sulphuric acid and copper sulphate solution
used to make Fehling’s reagent - test for reducing sugar
used to make Tollen’s reagent - test for an aldehyde
barium sulphate is widely used in plants
