Answer:
Lemon juice has lowest pH.
Explanation:
pH is the negative log of hydrogen ion concentration. By increasing the Hydrogen ion concentration pH will decrease.
pH = -log [H⁺]
According to pH scale,
The pH of 7 is consider neutral. The pH below the 7 is consider acidic and above the 7 is basic.
The sodium hydroxide is strongest base because it fully dissociate into ions.
It dissociate to gives the sodium and hydroxyl ions and solution became more basic.
NaOH → Na⁺(aq) + OH⁻(aq)
Its pH is 12. It is also known as caustic soda.
The pH of blood is vary from 7.35 - 7.45. it is slightly alkaline.
The pH of lemon juice is ranging between 2-3.
The pH of tap water is ranging between 6-8.5.
From above given information it can be noticed that lemon juice have lowest pH i.e 2-3. It is acidic, because its pH is less than 7.
Answer:pure water is neutral . Lake water is acidic. Baking soda and soapy water are basic.
Explanation: 7 is neutral. The higher on the ph scale like 1-6 is acidic. The lower on the scale 8-13 is base or alkaline.

Explanation:
Answer:
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
