Bitter tasting food is ______ in nature.

 Bitter tasting food is ______ in nature.

1
Alkaline
2
Acidic
3
Neutral
4
Bases
Correct Answer

The correct answer is Bases.

Key Points

  • Bitter-tasting food is basic in nature with a pH greater than 7. Examples are  Ca(OH)2, NaOH, NaHCO3.
  • Bases turn red litmus to blue.
  • Alkaline gives off OH- ions in water.

Additional Information

  • The sour taste of organic food materials is mainly caused by the presence of acidic materials.
  • Acids are sour in taste with a pH of less than 7. Examples are Vinegar, Tartaric acid, Citric acid, and Malic acid.
  • Acids give off H+ ions in water.
  • Acids turn blue litmus to red.
  • Acid and base react together to form salt and water and this reaction is known as neutralization.
  • Water is neutral with a pH value equal to 7.

Mistake Points

  • Bases are usually bitter to taste, turn red litmus paper blue, and release hydroxyl ions (OH) −1 in the solution medium responsible for their basicity.
  • Bases can be either water-soluble or they can be insoluble in water.
  • Water-soluble bases are known as alkalis, for eg. NaOH, KOH.
  • Therefore, we can easily conclude that All alkalis are bases but all bases are not alkalis.
