Carbon dioxide gas and a salt
1. acid/base 2. protolysis 3. reversible proton exchange 4. .... reactions
Hydrochloric acid and sodium hydroxide yield salt and water H+ + Cl- + Na+ + OH- --> Na+ + Cl- + H2OComment:In solutions you better leave unchanged ions ( Cl- and Na+) out of the balanced equation: called to be 'tribune ions' (people on the tribune don't take part in the 'match'):H+ + OH- --> H2O This looks simpler than: H+ + Cl - + Na + + OH- --> Na + + Cl - + H2O
Not by itself. A cup of salt may be a fraction of the total amount of salt in the world, but just sitting there, a cup of salt is a cup of salt.
It depends on how thinly the salt is spread.
acid + metal carbonate--> Salt+ Carbon dioxide+ water
Metal+Acid=Salt+Hydrogen
Metal Hydroxide + Acid = Metal Salt + Water
water
Water
Acid plus Base gives a Salt and Water. Acid plus Metal gives Hydrogen gas and a Salt.
acid+metal-->salt plus hydrogen
an ammonium salt
An acid plus a metal produces a salt of the acid plus Hydrogen gas. 2HCl + 2Na ---> 2NaCl + H2
Strong acid + metal acetate --> acetic acid (weak acid) + metal salt (of the strong acid)
OH(-) A hydroxide. base
hcl acid
