Write ionic equation for the reaction between potassium and an acid
What acid? HCl?
The molecular equation is as follows:
2K(s) + 2HCl(aq) ==> 2KCl(aq) + H2(g)
Convert to ionic equation.
2K(s) + 2H^+(aq) + 2Cl^-(aq) ==> 2K^+(aq) + 2Cl^-(aq) +H2(g)
The NET IONIC equation is
2K(s) + 2H^+(aq) ==> 2K^+(aq) + H2(g)
To write the ionic equation for the reaction between potassium (K) and an acid, we need to first determine the acid that is reacting with the potassium.
Let's assume that the acid is hydrochloric acid (HCl). The formula for hydrochloric acid is HCl, which means it dissociates into hydrogen ions (H+) and chloride ions (Cl-) when it is dissolved in water.
Now let's consider the reaction between potassium (K) and hydrochloric acid (HCl):
K(s) + HCl(aq) → ?
In this reaction, the potassium (K) will lose an electron to form a potassium cation (K+). The hydrogen ion (H+) from the hydrochloric acid will combine with the chloride ion (Cl-) to form hydrogen chloride (HCl).
The balanced ionic equation for the reaction between potassium and hydrochloric acid is:
K(s) + H+(aq) + Cl-(aq) → K+(aq) + Cl-(aq)
This equation represents the ionic species involved in the reaction, with H+ and K+ ions being the cations, and Cl- ions being the anions. The potassium cation (K+) and chloride anion (Cl-) are present on both sides of the equation, indicating that they are spectator ions and do not participate in the reaction.
Note: If a different acid is involved, the specific acid formula and its dissociation reaction would need to be considered for writing the ionic equation.
