why in reaction of acids and metals hydrogen gas and salt is produced?

Question

How hydrogen gas and salt produced during the reactiom of metals and acids

Answer 1

Hi! ang gagaling talaga magtanong ng mga Pinoy! Wooosh!

Anyway, talagang ganyan ang buhay. talagang pagpinagsama mo sila, eh un na ang tadhana.

Let's take the example below:

2HCl+ 2Na --> 2NaCl + H2

It gives off hydogen because the acid has hydrogen ions, and Chorine has strong electronegativity and the metal has electopositivity (ability to donate electrons). The hyrogen is replaced by Sodium. The result, hydogen gas is emitted, plus the metallic salt.

Answer 2

Acid and metallic reaction produce hidrogen gasoline in a good type of the circumstances. There are some metals that are inert to three acids besides, so no longer something is produced. in accordance to defiition of acids you've a proton there which will nicely be "replaced" into the metallic, so hidrgen gasoline receives released. the guideline is that in problem-free words the further lively metals can replace hidrogen from the acid. the different rule is that the more perfect acid continually reacts with the weaker acids salt(on your case the carbonate-that's the salt of H2CO3, that's seen an somewhat weak acid) and also you get the weaker acid and the more perfect acids salt. would seem as if this: STRONGACID+SALT1(of the wekaer one) -> weak ACID+ SALT2(of the more perfect one) or shall we take the carbonate get at the same time:HA is the more perfect acid,MeCO3 is the carbonate,MeA is the salt of the more perfect acid HA+MeCO3-> H2CO3 +MeA As you would comprehend hidrogen carbonate is an somewhat weak acid, and is willsplit into water and carbon dioxid, and this can be the gasoline that you spot.

Answer 3

well ur question is not very clear,however ill take a shot.
this is becuz the metal ion replaces the hydrogen ion present in the acid (as you know for ana cid 2 be an acid there must be a hydrogen ion present) and as a result of the metal replacin the
hydrogen ion u get the salt th ehydrogen gas then is left by itself as a product 4 it has nothing to react withfor example:
na(s)+HCl(aq)-------nacl(aq)+ H2(g)
the metal replaces the hydrogen ion .

Answer 4

an acid is composed of an anion A and H

The rection with the metal is

AH +M --> AM + 1/2 H2

Often thistake place iwater and instead of having M you have MOH and water is produced

Answer 5

it's in how the metal complex reacts. it normally results in a metal hydroxide complex, and H2 is produced as a byproduct. if the reaction is quick enough it will catch on fire...

Answer 6

That's a property of metals...
