The protons in acetylene (C2H2) are very weakly acidic. With a strong base (eg. sodium hydride, NaH), they can be abstracted, giving the corresponding metal acetylide (NaC2H, and Hydrogen, H2).

What theory describes an acid as a proton and a base as a proton acceptor?
Brønsted-Lowry acid-base theory
How can you justify that bronsted-lowery concept of acid and base?
It is based on the proton. A proton acceptor is a base whereas a proton donour is known as an acid.
Is a substance that is a proton donor a acid or base?
ACID
What makes nitric acid an acid?
The definition of acids is a substance which is a proton (H+) donor in chemical reactions. Nitric acid is an acid because it donates a proton to water.
What is transferred between a conjugate acid base pair?
a proton

What are the bronsted - lowry definition of acid and base?
Arrhenius: Acid is a proton (H+) donor. Base is a -OH^- (hydroxyl) donor.B-L: Acid is a proton donor. Base is a proton acceptor.

The definition of acids is a substance which is a proton (H+) donor in chemical reactions. Nitric acid is an acid because it donates a proton to water.
Does a weak acid gain a proton?
No, an acid, weak or strong, donates a proton. It is a base that gains one.
Is a vinegar a acid or a base?
Vinegar is dilute acetic acid, which is an acid.
What is transferred between a conjugate acid base pair?
a proton
An acid that forms when a base gains a proton?
conjugate acid
Why acetylene is stronger acid Than ethylene?

Why acetylene is more acidic than ethylene?
The acidity of a substance is measured by its pKa. A given acid will give up its proton to the base of an acid with a higher pKa value. The base of a given acid with deprotonate an acid with a lower pKa value.The pKa of water is 15.74The pKa of ammonia is 34The pKa of acetylene is 25What this means is that acetylene will not act as an acid in water and there will be essentially no dissociation of the hydrogen ion (the concentration of HCC- is essentially zero). This means that acetylene can dissociate in ammonia, but only to a small extent. Acetylene is considered a weak acid in ammonia.See the Web Link for a very good explanation of this (with a direct comparison of water, ammonia, and acetylene). It is a pdf file.
An acid is a(n)?
