Why H atoms of acetylene slightly acidic and replaceable by metals?
It is due to two reasons, 1- C-C short bond length which is responsible to almost localized the pi electrons between two nuclei and to decrease the electron density at opposite side of both nuclei and 2- sp1 hybridized orbitals of carbon which are responsible to attract the electron pair of C-H bond.
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.
Is cysteine acidic?
It's not. It's neutral and slightly polar.
Is hydrogen sulfide gas soluble in water?
slightly soluble, it will make water slightly acidic
Is milk an acid base or neutral?
Milk has a pH slightly acidic.
Which is more acetic water or acetylene?
Do you mean acidic? Water has a pKa of ~14 and acetylene has a pKa of ~25, so water is more acidic.

Why acetylene shows acidic character?
because it is an organic compound and its functional group is co-oh which is an acid so due to its acidic functional group its characteristics became acidic
Tea is an acid or base?
acidic acidic acidic
Is pear juice acidic?

Is coffee an acidic?
yes. coffee has a ph of 5, which makes it slightly more acidic than milk, and slightly less acidic than tomato juice.
Is alcohol acidic or alkaline?
Very acidic indeed. So are coffee and tea.
In what sense is acetylene a proton acid?
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).
Is aluminum nitrate an acid or a base?
Aluminum nitrate is a slightly acidic salt.
Is saliva acidic or basic?
It is slightly acidic with a pH ranging from 6 to 7.
