2NaOH (aq) + H2SO4 (aq) →Na2SO4(aq) + 2H2O(l)
1. What is the Arrhenius acid and Arrhenius base?
2. What are the spectator ions?
idk that's why i looked this up
To determine the Arrhenius acid and Arrhenius base in a chemical reaction, we need to understand what these terms mean.
1. Arrhenius Acid: An Arrhenius acid is a substance that dissociates in water to produce hydrogen ions (H+). The hydrogen ions can be identified by a positive charge or the symbol H+. In the given reaction, H2SO4 is the Arrhenius acid since it donates H+ ions when dissolved in water.
2. Arrhenius Base: An Arrhenius base is a substance that dissociates in water to produce hydroxide ions (OH-). The hydroxide ions can be identified by a negative charge or the symbol OH-. In the given reaction, NaOH is the Arrhenius base as it releases OH- ions when dissolved in water.
Now, let's determine the spectator ions. Spectator ions are the ions that do not actively participate in the chemical reaction and remain unchanged throughout the reaction. To identify spectator ions, we need to compare the cations (positive ions) and anions (negative ions) present on both sides of the reaction.
In this reaction:
- Na+ cations and SO4^2- anions appear on both the reactant (left) and product (right) sides.
- Only the H+ cations from the acid and OH- anions from the base participate in the reaction to form H2O and Na2SO4.
Therefore, Na+ and SO4^2- ions are the spectator ions since they do not undergo any chemical change in the reaction.
To summarize:
1. The Arrhenius acid in the reaction is H2SO4.
2. The Arrhenius base in the reaction is NaOH.
3. The spectator ions are Na+ and SO4^2-.
