Read the scenario.
Hydrogen chloride (HCl) and potassium hydroxide (NaOH) react.
What products are formed from this reaction?
NaOH + HCl → NaCl + H2O
thank you
Note that you wrote potassium hydroxide but gave the formula of NaOH which is sodium hydroxide.
To determine the products formed from the reaction between hydrogen chloride (HCl) and potassium hydroxide (NaOH), we need to understand the concept of a chemical reaction and the types of reactions involved.
1. Chemical reaction: A chemical reaction occurs when two or more substances interact and result in the formation of new substances with different properties than the original ones.
2. Reaction types: There are several types of chemical reactions, including acid-base reactions, precipitation reactions, redox reactions, etc. In this scenario, we are dealing with an acid-base reaction.
3. Acid-base reaction: An acid-base reaction involves the transfer of a proton (H⁺) from an acid to a base, resulting in the formation of water and a salt. In the case of HCl (acid) and NaOH (base), water and a salt will be produced.
Now, let's determine the products of the reaction between HCl and NaOH:
HCl + NaOH → ?
- HCl is the acid because it donates a proton (H⁺).
- NaOH is the base because it accepts a proton (H⁺).
When an acid reacts with a base, they neutralize each other to form water (H₂O) and a salt. In this case:
HCl + NaOH → H₂O + ?
To identify the salt formed, we need to consider the cations and anions of the reactants:
- HCl contains the chloride ion (Cl⁻).
- NaOH contains the sodium ion (Na⁺) and the hydroxide ion (OH⁻).
When chloride ion (Cl⁻) reacts with sodium ion (Na⁺), they combine to form sodium chloride (NaCl), which is a salt.
HCl + NaOH → H₂O + NaCl
Therefore, the products formed from the reaction between hydrogen chloride (HCl) and potassium hydroxide (NaOH) are water (H₂O) and sodium chloride (NaCl).
