Use blue litmus paper. This is an indicator that can safely determine whether it is a base or an acid by changing color in response to the substance. This color indicates whether it is an acid or a base. Refer to the pH scale to see if the substance is basic or acidic.
Answer: 0.0274 M
Explanation:-
The balanced chemical solution is:
According to the neutralization law,
where,
= molarity of 
solution = 0.117 M
= volume of solution = 23.4 ml
= molarity of 
solution = ?
= volume of solution = 100.0 ml
= valency of = 1
= valency of = 1
Therefore, the concentration of ammonia in a solution will be 0.0274 M
Well, elements are arranged based on a number of factors.
Left to right, elements are arranged based on atomic number. The atomic numbers of the elements are increasing by 1 as you move from left to right.
Top to bottom is based on increasing atomic radius. As you move from top to bottom, each succeeding element in a group gets an additional electron shell, increasing the atomic radius as you move down.
