Answer:
anion
Explanation:
anion undergoes reduction.
cation undergoes oxidation.
The ions are categorized according to the process of oxidation and reduction. The ion usually undergoes reduction is an anion.
What is reduction?A process involving the partial or complete gain of electrons and loss of oxygen. The ions acquire a net negative charge on them.
Thus, anions usually undergo a reduction.

If you put 100g of NaOH in cube form and 200g of NaOH in powered form which will react with HCl at a faster rate? Explain why
Answer:
200g of NaOH in powered form will react with HCl at a faster rate
Explanation:
200g of NaOH in powered form will react with HCl at a faster rate because it is in powdered form and it will have high surface area to volume ration and hence high reactivity and rate of reaction as compared to the cube NaOH.
A catalyst increases the rate of a chemical reaction by
Lowering the heat of reaction
Increasing the activation energy
Lowering the activation energy
Changing the position of equilibrium
Answer:
Lowering the activation energy
Explanation:
A catalyst does not participate in the reaction, instead it offers the reaction an alternative pathway by lowering the activation energy. This new pathway is faster and the rate of reaction is increased.
