Most common acids + bases (1 Viewer)

[lucyinthehole]

sorry if this has been asked already or if there's a really obvious way of finding this out (in that case just point me in the right direction), but if it's not too much trouble, can someone post a list of all the acids and bases they expect us to know the formulae of? remember, you'd be revising in the process :uhhuh:

Of the top of my head...
Citric acid (C6H8O7)
Acetic acid (CH3COOH)
Sulfuric acid (H2SO4)
Hydrochloric acid (HCl)
Phosphoric acid (H3PO4)
Nitric acid (HNO3)
Carbonic acid (H2CO3)

Sodium hydroxide (NaOH)
Ammonia (NH3)

That's all I can think of that they'd expect you to know. And they might not even expect you to know all of them, but it couldn't hurt

Citric acid (C6H8O7)
Acetic acid (CH3COOH)
Sulfuric acid (H2SO4)
Hydrochloric acid (HCl)

these four are in the syllabus, sorry copied from Paroissien

 

[Paroissien]

Wow, that's not to bad.
BTW citric acid is 2-hydroxypropane-1,2,3-tricarboxylic acid but I highly doubt you are expected to know that

The molecular formula for citric acid's mentioned in the syllabus so...yeah lol

 

[d_elmo]

remember that u not only have to know the acids and bases but u would probably be expected to know if they were weak or strong as well

*gulp* any help on that, helper?

 

[xeriphic]

for acids

HCl
H2SO4
HNO3

are strong acids where the its single arrow --->

other acids like CH3COOH, H2CO3 are weak acids where it has double arrows <--->

for base I would say they only expect you to know NaOH as strong, any other base they would tell you

hey anyone kno some common bases found around the home? all i can think of is bicarb of soda...any else?

 

[helper]

Citric, acetic and hydrochloric you need to know in terms of there relative strengths. and how much each ionises.

IE the stronger the acid is the more it ionised.

IE HCl strong, other two are weak

 

[xeriphic]

detergents, window cleaner

 

[Shards]

btw, citric is stronger than ethanoic

 

[xeriphic]

hydrochloric > citric > ethnoic

ammonia (NH3)

 

[sub]

yeah i saw that above...but there's a question in some paper (some trial most likely) that sed name three acids and bases found around the home...also how many ppl keep ammonia in their cupboard? i was looking for stuff used everyday around the home...came up with bicarb of soda only

 

[helper]

A lot of people have cloudy ammonia in there home as a cleaning substance.
Caustic soda (NaOH) is commonly found in garages as a drain cleaner
