A.Lime water
B.Vinegar
C.Tooth paste
D.Stomach juices
E.Lemon juice
F.Baking soda solution
G.Milk of magnesia
H.Ammonia solution
I.Shampoo
J.Aerated drinks.

Answer 1

:Hint:The utilization of the pH scale is one pragmatic method of quantitatively deciding how acidic something is. On the off chance that the pH of an answer is under 7, it is acidic. In the event that the pH is 7, the solution is alkaline and if the pH is more prominent than 7, the solution is base. This scale demonstrates the measure of real $H^{+}$ particles (acidity) coasting around in the solution, which is straightforwardly identified with the meaning of an acid.

Complete answer:
First, let us try to understand what an Acid is. Acid is a solution which gives $H^{+}$ ions in an aqueous solution. And a Base is a solution which gives $O{H}^{-}$ ions in aqueous solution.
So, now let us divided the given options based on the above understanding-
A.Lime water – Base
B.Vinegar – Acid
C.Toothpaste – Base
D.Stomach juices – Acid
E.Lemon Juice – Acid
F.Baking Soda Solution – Base
G.Milk of Magnesia – Base
H.Ammonia Solution – Base
I.Shampoo – Alkaline
J.Aerated Drinks - Acid

Additional Information:
A compound that contains an $OH$ group likewise contains a metal particle; at that point it is a base. The presence of the metal particle demonstrates that the compound contains ionic bonds. Hence, to whatever degree this compound breaks down in water, the metal particle will separate from the $OH$ group. The solution of "free" $OH$ groups, for example hydroxide particles, brings about an answer that is base. Compounds that contain "pseudo metal" cations, for example, ammonium, $N{H_4}^{+}$ , clung to an $OH$ group are additionally basic.

Note:
On the off chance that the compound being referred to in the question doesn't contain a metal particle, for example on the off chance that it contains just covalent bonds, at that point it is either acidic or non-acidic. There are no particles that contain just covalent bonds that separate in water to yield hydroxide particles! As you probably are aware, water, $HO-H$ , is non-acidic. It is the norm by which we measure acidity: aqueous solutions that contain concentration of hydroxide ion greater than that in water are basic, while solutions in which the centralization of hydronium ion is bigger than that in water are acidic.
