If you added potassium to hydrochloric acid, it would produce potassium chloride (a potassium salt) and hydrogen gas as in the equation below:
2K(s) + 2HCl(aq) --> 2KCl(aq) + H2 (g)This reaction is the same for all metals.
Acid + Metal = Metal salt + Hydrogen gasOther reactions:
Adding an acid to a metal hydroxide gives a metal salt and water.
Adding an acid to a metal carbonate give a metal salt and carbon dioxide gas.
Acid + Alkali -> Salt + Water For this case, Hydrochloric acid + Potassium hydroxide -> Potassium chloride + water HCl + KOH -> KCl + H2O
2hcl- + k2co3====>2h2co3+2kcl
There is a vigorous and exothermic reaction. The hydrochloric acid and zinc react to produce zinc chloride and hydrogen gas. Large amounts of heat are also released.
No gas is released when sulphur is added to dilute hydrochloric acid.
Potassium Dichromate (VI) can be acidified with sulphuric acid AND hydrochloric acid! Note that another common oxidising agent ' Acidified Potassium Manganate (VII)' is sometimes used although this one can only be acidified with sulphuric acid not hydrochloric as the Manganate (VII) oxodises the Cl- ion instead!

pottasium chlorate

is soluble in water and will fizz when hydrochloric acid is added
No gas is released when sulphur is added to dilute hydrochloric acid.
This element is iodine - added as potassium iodide or potassium iodate.

A cyanide compound such as potassium cyanide is highly soluble in water and dissolves as easily as table salt. As for the speed of reaction with other chemicals, that really depends which chemicals we are talking about, however, it does react rapidly to some chemicals, since as hydrochloric acid, which when added to a solution of potassium cyanide would produce an immediate release of highly toxic cyanogen gas.
is Ca(OH)2 is soluble in water and will hissing when hydrochloric acid is added
It would depend on which acid and alkali were involved, the general rule is that adding an acid to an alkali will produce a salt and water. Sulphuric acid and sodium hydroxide would give sodium sulphate + water Hydrochloric acid and potassium carbonate would give potassium chloride and water and carbon dioxide etc
This element is iodine, added as potassium iodide or potassium iodate.
