An ionic compound is a compound between a metal and a non metal where the metal (normally from group 1 or 2) transferrs an electron to the non metal ( most commonly from group 6 or 7) . this is so that both atoms have a full outer shell of electrons. the metal gains a positive charge and the non metal a negative charge. they are held together by electrostatic forces of attraction. an example would be sodium chloride (salt) sodium is in group 1 and chlorine in group 7 so sodium transfers one electron :)
Answer:
Option 3.
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Explanation:
To know which option is correct, we must have an ideal of what is acid–base neutralization.
Neutralization is a reaction involving an acid and a base which produces salt and water only.
With the above information, we can easily detect the equation describing acid-base neutralization reaction by considering the products of each reaction to see the one that has water as part of the products.
From the question given above, only the 3rd equation gas water as part of the products i.e
LiOH(aq) + HNO₃(aq) —> LiNO₃(aq) + H₂O(l)
Hence, equation 3 is an acid-base neutralization reaction
