writing balanced chemical reaction of K2CO3 (s) with HCl (aq)??
You need 2 H for each CO3, so
2HCl + K2CO3 -> 2KCl + H2CO3
To write a balanced chemical equation for the reaction between potassium carbonate (K2CO3) and hydrochloric acid (HCl), we need to take into account the properties and charges of the ions involved.
Step 1: Write the chemical formulas for the reactants.
K2CO3 + HCl
Step 2: Identify the elements and their oxidation states.
In K2CO3, potassium (K) has a +1 oxidation state, carbon (C) has a +4 oxidation state, and oxygen (O) has a -2 oxidation state. In HCl, hydrogen (H) has a +1 oxidation state, and chlorine (Cl) has a -1 oxidation state.
Step 3: Determine the products by swapping the ions.
The reaction will form potassium chloride (KCl) and carbonic acid (H2CO3).
Step 4: Write the balanced equation by ensuring the number of each atom is equal on both sides.
K2CO3 + 2HCl → 2KCl + H2CO3
Overall, the balanced chemical equation for the reaction between potassium carbonate (K2CO3) and hydrochloric acid (HCl) is:
K2CO3 + 2HCl → 2KCl + H2CO3
