Which of the following is incorrect statement about boric acid?

Which of the following is incorrect for H3BO3. Solution : Boric acid (H3BO3) is a weak monobasic acid with Ka=1.0×10-9. It may be noted that boric acid does not act as a protonic acid (i.e, proton donor) but behaves s a Lewis acid by accepting a pair of electrons from OH- ion.

Which is false in case of boric acid H3BO3?

Answer. Explanation: boric acid is a weak monobasic acid.

What are the properties of boric acid?

Physical Properties of Boric Acid –

  • It is a colorless or white crystalline solid at room temperature.
  • Its molar mass is 61.83 g/mol.
  • Its melting point is 170.9℃.
  • Its boiling point is 300℃.
  • It is soluble in water.

What are the benefits of boric acid?

This product works by replenishing normal vaginal acidity and balancing vaginal flora (helpful bacteria). Vaginal boric acid is a homeopathic prescription medicine used to treat vaginal yeast infections and relieve symptoms such as burning, itching, and odor.

What is the effect of heat on boric acid?

When boric acid is heated it converts to metabolic acid which on further heating gives boron trioxide. Answer: On strong heating, first the Boric acid (H3BO3) breaks up into Metaboric acid (HBO2) and Water (H2O). On further heating, the Metaboric acid breaks up into Boric oxide (B2O3) and Water.

Why Boric acid is considered as a weak acid?

Boric acid is a weak monobasic acid because it does not dissociate completely to give H+ ions but it can form metaborate by accepting OH- ions from water.

Does boric acid still work if it gets wet?

Boric acid is useless when wet, which may make its use impractical in some areas. And boric acid is toxic to humans and pets as well; it can cause nausea, vomiting, abdominal cramps and even death, from as little as 5 grams in infants and 5 to 20 grams in adults.

What happen when boric acid is added to water?

When boric acid is added to water it accepts a pair of electrons from OH- ion and releases proton, thus forming acidic solution .

Is it safe to touch boric acid?

What are some signs and symptoms from a brief exposure to boric acid? Boric acid is low in toxicity if eaten or if it contacts skin. However, in the form of borax, it can be corrosive to the eye. Borax can also be irritating to the skin.

Can I mix boric acid with water and spray it?

Combine 2 tbsp. of powdered boric acid and 3 cups of water into an empty spray bottle. Shake the bottle vigorously to thoroughly mix the ingredients.

What does boric acid react with?

Boric acid reacts with alcohols to form borate esters, B(OR)3 where R is alkyl or aryl. A dehydrating agent, such as concentrated sulfuric acid is typically added: B(OH)3 + 3 ROH → B(OR)3 + 3 H2O. A variety of salts are also known, involving the planar trigonal BO33– borate anion.

How do you beat chronic BV?

Limited data suggest that an oral nitroimidazole (metronidazole or tinidazole 500 mg twice daily for 7 days) followed by intravaginal boric acid 600 mg daily for 21 days and then suppressive 0.75% metronidazole gel twice weekly for 4–6 months for those women in remission might be an option for women with recurrent BV ( …

Will my BV ever go away?

Bacterial vaginosis often clears up on its own. But in some women it doesn’t go away on its own. And for many women it comes back after it has cleared up. Antibiotic treatment works for some women but not others.
