Explanation

The pH scale ranges from 1 to 14, with:

• 1-6 being acidic
• 7 being neutral (neither acidic nor basic)
• 8-14 being basic (alkaline)

Explanation

• Litmus paper is a simple and effective way to test whether a substance is an acid or a base.
• It turns red in acidic solutions and blue in basic solutions.

Explanation

• Ascorbic acid, also known as Vitamin C, is found in various fruits and vegetables.
• But Alma (Emblica officinalis) and citrus fruits like oranges, lemons, and grapefruits are particularly rich in it.

Explanation

• Lactic acid is a natural preservative found in fermented foods like yogurt, cheese, and sauerkraut.
• It's produced during the fermentation process when bacteria like Lactobacillus convert sugars into acid.

Explanation

• Tartaric acid is a white, crystalline organic acid that occurs naturally in many fruits, most notably in grapes and tamarinds.
• It also found in bananas, avocados, and citrus fruits.

Explanation

• Neutralization is a chemical reaction where an acid and a base combine to form a neutral solution, neither acidic nor basic, with a pH of 7.
• This process is commonly seen in reactions between strong acids and strong bases, resulting in the formation of a salt and water.

Explanation

• A base is a substance that produces hydroxide ions (OH-) in an aqueous solution, making the solution basic.
• Examples of bases include sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2), and ammonium hydroxide (NH4OH).

Explanation

• An acid is a substance that donates a proton (H+ ion) in a reaction, increasing the concentration of hydrogen ions in an aqueous solution.
• Examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH).

Explanation

Explanation

• Hydrogen and Oxygen combining to form water, which is an example of a synthesis reaction: 2H2 + O2 → 2H2O
• In this reaction, two substances (hydrogen and oxygen) combine to form a new compound (water).
