Inorganic Chemistry Flashcards
What happens when group 1 react with water
Metal + water —–> Metal hydroxide + hydrogen
What are the three observations of Lithium
- Reactions slowly
- Sloid moves on the surface ( floats on the surface)
- Fizzing
What three observations Sodium (na)
- reacts more vigorously
- vigorous fizzing
- Dissolves quickly
- moves rapidly on the surface
What are the observations of Potassium
- Lilac flame
- Reacts more vigorously than sodium
- dissolves quickly
- floats rapidly on the surface
what are the physical trends of Group 1 metals
- reactivity increases
- Density increases
- melting point decreases
- Boiling point decreases
what do group 7 forms when they react with water
they from an acid
what are properties of a group 7 elements
- halogens
- Diatomic
- non- metals
- Reactivity decreases as you go down the group
- melting point and boiling point increases as you go down the group
what state and appearance is iodine at room temperature
Dark grey crystalline solid
what happens when Iodine is heated
Purple vapour
What colour is iodine in Solution
Dark Brown
what state and appearance is Chlorine at room temperature
Green gas
what colour is Chlorine in solution
colourless
what state and appearance is Bromie
Red- brown liquid
what colour is bromine in a solution
orange
What is displacement
when the more reactive halogen displaces the less receive halogen from an aqueous solution of it’s halide
what happens when chlorine water reacts with Potassium Chloride solution
Nothing it can not displace itself
What happens when chlorine water reacts with potassium bromide solution
form potassium chloride + bromide
ORANGE solution formed
What happens when chlorine water reacts with Potassium Iodine
potassium chloride + iodine
Brown solution
What happens when Bromide water reacts with Potassium chloride
No reaction
bromide is less reactive than chlorine
What happens when Bromide water reacts with Potassium bromide
no reaction
What happens when Bromide water reacts with potassium iodine
potassium bromide + iodine
Brown solution
what happens when Iodine water reacts with Potassium Chloride solution
No reaction
what happens when Iodine water reacts with Potassium Bromide
no reaction
less reactive
what happens when Iodine water reacts with Potassium Iodine
no reaction
can’t displace itself
