Is ammonia basic?

Question

Also, is chlorine acidic or basic? What's the world's most powerful base?

Answer 1

Ammonia is a base. If you mix household ammonia cleaner with vinegar (acetic acid) the vinegar will neutralize it and reduce it's cleaning ability. I don't know what the most powerful base is, but sodium hydroxide (otherwise known as "lye", the active ingredient in crystal Drano) is a very strong and highly corrosive base that can eat right through your skin and dissolve paint and rust. It's also easily available in any supermarket. Chlorine itself is just an element, but when it's in a solution such as household chlorine bleach, it alkalinity is pretty high and acts as a strong base.

Answer 2

Ammonia is a base, but can be used as an acid. (See source.)

I'm not sure about chlorine, but I'm thinking it's acidic (think hydrochloric acid).

Finally, sodium hydroxide is a pretty strong base and can exist in water. There are stronger bases, which can't exist in water, called superbases.

Answer 3

Ammonia is a base, chlorine in and of itself isn't acidic or basic. Any hydroxide compound that is highly soluble in water will be very, very basic, but any hydroxide compound as well as ammonia, is going to hurt like a b*tch if it gets on your skin. aka, don't f*ck around with any of them.

Ammonia is more basic, because on the acid base table, you start at the bottom right to find the strongest base (SB), and ammonia comes before oxygen.

Answer 5

NH3 can act as a base by accepting a proton, to become, {NH4}+

I do not know about the most powerful, but I think NaOH may be.

Answer 6

Yes, ammonia is basic
Chlorine is considered strongly acidic

Bases can be considered to be either proton acceptors or electron donors. Chlorine, as a Halogen, is one of the strongest electron holding elements so it is NOT a base. Acids are compounds or elements that are likely to donate an electron. Hydrogen is not thought of as acid, but it is the element most likely to donate an electron to a chemical reaction (because of its position on the Periodic Table).

Normally only some chemicals are thought of as acids or bases not all chemicals are. None of the Noble gases would be either acids or bases since they have a stable electron configuration and won't donate or accept others, they don't participate in chemical reactions.

According to Wikipedia: http://en.wikipedia.org/wiki/Base_%28chemistry%29#Strong_bases
"In chemistry, a base is most commonly thought of as a substance that can accept protons. This refers to the Brønsted-Lowry theory of acids and bases. Alternate definitions of bases include electron pair donors (Lewis), as sources of hydroxide anions (Arrhenius) and can be (commonly) thought of as any chemical compound that, when dissolved in water, gives a solution with a pH higher than 7.0. Examples of simple bases are sodium hydroxide and ammonia."

According to Wikipedia: http://en.wikipedia.org/wiki/Acid
"An acid (often represented by the generic formula HA [H+A-]) is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0. That approximates the modern definition of Johannes Nicolaus Brønsted and Martin Lowry, who independently defined an acid as a compound which donates a hydrogen ion (H+) to another compound (called a base)."

Look at this Wikipedia Graphic: http://en.wikipedia.org/wiki/Image:PH_scale.png
And you can see a list of various acids and bases.
Battery Acid is listed as the strongest acid, so low it goes off the chart at -0.8 pH
Lye is listed as the strongest base at 13.5 ph, but Rubidium hydroxide is considered to be the strongest base.

According to Wikipedia:
"A strong base is a basic chemical compound that is able to deprotonate very weak acids in an acid-base reaction. Compounds with a pKa of more than about 13 are called strong bases. Common examples of strong bases are the hydroxides of alkali metals and alkaline earth metals like NaOH and Ca(OH)2. Very strong bases are even able to deprotonate very weakly acidic C-H groups in the absence of water. Hydroxide compounds in order of strongest to weakest:

Potassium hydroxide (KOH)
Barium hydroxide (Ba(OH)2)
Cesium hydroxide (CsOH)
Sodium hydroxide (NaOH)
Strontium hydroxide (Sr(OH)2)
Calcium hydroxide (Ca(OH)2)
Lithium hydroxide (LiOH)
Rubidium hydroxide (RbOH) "

Bleach, which has chlorine in it is a base, but hydrochloric acid is an acid with a pH of -8.0.

Chlorine and hydrogen will give you HCl; hydrochloric acid.
