Answer:The correct answer is option 4.
Explanation:
Arrhenius acids are those compounds which gives 
ions when dissolved in their aqueous solution.
Arrhenius bases are those compounds which gives 
ions when dissolved in their aqueous solution.
are Arrhenius acids because they form ions in their respective aqueous solution.
Hence, the correct answer is option 4.
Q1. They are highly reactive. Q2. High reactivity, nonmetallic. Q3. Oxygen has an ion charge of -2. Q4. LiCl I believe. Q5. How electrons are shared. Q6 1. Q7. Share 2 valence electrons, I believe.
A common use of bases is to reduce indigestion. Hence, option D is correct.
<h3>What is the base?</h3>
A base is a substance that can neutralize the acid by reacting with hydrogen ions.
Bases are substances whose solutions have a pH value of more than 7. Bases are bitter in taste.
Whereas acids are the substances whose solutions have a pH value of less than 7. Acids are sour in taste.
When an excess of acid is formed in the human stomach then an antacid tablet which is basically a base is consumed that helps in reducing indigestion.
Therefore, we can conclude that the common use of bases is to reduce indigestion.
