Answer:Ethyne
Explanation:
Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.
The PH of the solution of HCl is calculated as below
Ph= - log H^+
calculate the hydrogen ion concentration
by first write the ionic equation for dissociation of HCl
HCl = H^+ + Cl^-
since the mole ratio between HCl to H^+ is 1:1 the concentration of H^+ =0.01 M
Ph is therefore = - log 0.01 = 2
HCl has a PH of 2
