name an acid when given the formula of acid
a) HNO2 I put hydronitrogen acid no..don't include the "hydro" but I learned that if it's NO3 then the ending is "ate" and that NO2 ending is "ite" thus "ite before ate I say" so what do you think HNO2 is?
H3Po4 I put Hydro phosphoric acid once again..no "hydro" needed here
then it says write the chmical formula of an acid
a) Hydrocyanic acid didnt know that one cyanide is Cn thus HCn is the formula
b) it said hypochlorous acid didnt know that one either hypochlorous acid is HClO
I suggest looking up "naming acids" on google. The first links I saw looked good.
~C~
Error made on the 2nd one: HNO2 is nitrous acid.
H3Po4 I put Hydro phosphoric acid once again..no "hydro" needed here
Actually i meant H3PO4, so would it just be phosphoric acid?
Yes
thanks!
no problem =)
I still sugest you go and look up "naming acids" on google. It will help alot.
Here is a good lesson in suffixes and prefixes.
"normal" acid is stem + ic.
1 less O, change ic to ous.
2 fewer O, add prefix of hypo...+ ous
1 more O, add prefix per to normal.
For example.
HClO4 PERchlorIC acid (Per + stem + ic)
HClO3 chlorIC acid (stem + ic)(Normal)
HClO2 chlorOUS (stem + ous)
HClO HYPOchlorOUS acid (hypo + stem + ous)
HCl This is a binary acid (not ternary) so it is named by the usual method which is prefix of hydro + stem + ic) HYDROchlorIC
Of course you must know what the "normal" acids are.
HNO3 is nitrIC acid.
H3PO4 is phosphorIC acid.
H2CO3 is carbonIC acid.
H2SO4 is sulfurIC acid.
HClO3 is chlorIC acid.
HBrO3 is bromIC acid.
HIO3 is iodIC acid.
All of this may look confusing but just look at the periodic table to see where the central element of each acid (C,N,S,P,Cl,Br,I) is located. columns IV, V, VI, VII (or 14, 15, 16, 17 depending on the system your prof is using for the periodic table).
