Chemical salt??????? (1 Viewer)

[jim_bob2004]

Can anyone tell me the full chemical equation for the neutralisation reaction of sodium carbonate (Na2CO3) and aceytesalic acid (Asprin) C9H8O4, what is the salt formed?????

 

[CM_Tutor]

Sodium carbonate can be neutralised by an acid, such as hydrochloric acid, in which case the salt is sodium chloride.

Na₂CO_{3 (aq)} + 2HCl_(aq) ---> 2 NaCl_(aq) + CO_{2 (g)} + H₂O_(l)

Aspirin, or acetylsalicylic acid will react to form acetylsalicylate salts, such as sodium acetylsalicylate - NaC₉H₇O₄ - on reaction with an approriate base. It is a monoprotic weak acid, and thus its salts are weak bases.

Thanks that helps alot, so in the balance equation, the molar ratio is 1:1 so there is no difference in the number of moles?????

 

[kalinda]

yes its just a one to one ratio and therefore no difference in moles

They do in the main chemistry forum, and in the Maths fora, and I'm trying to find out if there's a good reason that HTML is off in this one.

And it is now on in this, and all other Chemistry sub-fora. So... we can start to type equations properly.

And jim_bob2004 and kalinda, the ratio in the equation I typed was actually 1:2 for Na₂CO₃:HCl, but it'd be 1:1 for aspirin:sodium hydroxide.
