How do buffers work in chemistry to maintain a stable pH level?
Buffers in chemistry work by resisting changes in pH when an acid or base is added. They contain a weak acid and its conjugate base, or a weak base and its conjugate acid. When an acid is added, the base in the buffer neutralizes it, and when a base is added, the acid in the buffer neutralizes it. This helps maintain a stable pH level in a solution.
How does the titration of a weak base with a strong acid affect the pH of the solution?
When a weak base is titrated with a strong acid, the pH of the solution decreases. This is because the strong acid neutralizes the weak base, leading to an increase in the concentration of H ions in the solution, which lowers the pH.
Do antacid tablets contain a base that neutralizes stomach acid?
Yes, antacid tablets typically contain a base such as calcium carbonate, magnesium hydroxide, or aluminum hydroxide that helps neutralize stomach acid by reacting with it to form a salt and water. This helps to relieve symptoms of heartburn and indigestion.
Why does a buffer solution will change in pH upon addition of acid or base?
Buffering compounds are weakly ionised, addition of hydrogen or hydroxide ions (in modest amounts), shift the degree of ionisation of the buffer which produces an increase or decrease in the hydrogen or hydroxide ions provided by the buffer itself. This change in ionisation of the buffering compound approximately compensates for the addition.
Is the conjugate of a strong base is a weak acid?
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.
What is the name of a fluid that neutralizes stomach acid?
Any Base will neutralize a acid. Are you wanting a specific answer? if so, try Baking Soda, Pepto-bismol, or any antacid in the marketplace. None of these (except Pepto-bismol) are actually fluids, but all of them will do the job. Stomach acid is actually a weak form of Hydrocloric acid. Hope this helps.

Is Demerol a base or acid?
Demerol is a weak base. I know this because it's not well absorbed in the stomach (weak bases ionize in acid). Some clients will take antacids to lower their stomach PH and abuse demerol this way.

Is CHOOH a weak acid or a weak base?
The formic acid is a weak acid.
What combinations of compounds will make a buffer when mixed?
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride
Is stomach acid weak?
Stomach juice is acidic. Because of hcl acid.
Which statement always accurately describes acids and bases a the conjugate base of a weak acid is a strong base b the conjugate acid of a weak base is a weak acid c strong acids and st?
b) The conjugate acid of a weak base is a weak acid. When a base accepts a proton to form its conjugate acid, it tends to be a weak acid because it does not easily donate a proton back. This relationship is governed by the principles of acid-base equilibrium.
Is hcoo-a weak base?
HCOO- is the conjugate base of formic acid (HCOOH) which is a weak acid. Therefore, HCOO- is a weak base.
