Why a mixture of ch3cooh and ch3coona can act as a buffer while a mixture of hcl and nacl can not?
Buffers are made out of what are called weak acids or weak bases. Mixtures of CH3COOH and CH3COONa can act as buffers because they don't break apart completely in solution like HCl and NaCl. As the CH3COOH and CH3COONa are in solution they keep the pH constant by either donating or accepting protons because they don't act like strong acids or bases. HCl is known as a strong acid where the hydrogen disassociates completely from the chloride. NaCl is not a buffer because it dissolves completely as welll
What are compounds that help keep a solutions acidity or alkalinity constant?
Compounds that help keep a solution's acidity or alkalinity (pH) constant are known are buffers.
What chemicals that help keep body fluids within a normal pH range are called?
The answer is a buffer or buffers.
What is the significance of acid and bases in your industry?
Acids and bases are chemical substances that release ions when dissolved in water. Acids are compounds that release positive hydrogen ions in water. Bases release hydroxide ions, which are compounds made of an oxygen and a hydrogen. Acids and bases are used around the house for cleaning, but the levels of acids and bases in the body are also important. The body needs a neutral pH and controls the amounts of acids and bases through processes involving the kidneys, lungs and blood. Acids and bases are found in foods, the environment and in chemicals including pharmaceuticals. The pH levels in the blood are required to stay neutral, which is at a level of 7. When a dieter eats acidic foods, the body uses a buffering system to neutralize the positive ions released from the acids. Conversely, bases are also controlled to keep the body from becoming too alkaline.
Why do bases and acids have to be kept in a safe place?
If you have children that like to be nosy you want to keep it in a high safe place so children dont get it in their eyes etc.
What are weak acids or weak bases that can react with strong acids or bases to keep the pH?
Solutions containing these mixtures are called buffers.
What mixtures that can react with acids or bases to keep the pH within a particular range?
These substances are called buffers.
What is the name of a weak acid or weak base that can react with strong acids or strong bases to keep the pH within particular range?
hydrogen ions
Why are buffers used in culture media?
Many bacteria produce metabolic acids that may lower the pH and inhibit their growth. To prevent this, buffers that produce a pH equilibrium are added to culture media to neutralize these acids.

What do buffers prevent?
They prevent a solution from becoming too acidic or too basic. Buffers help keep the pH at a specific level. For example, the human body uses buffers to maintain a pH of 7.4-7.6.
What importance are buffers to living organisms?
Buffers keep pH stable so there are not large changes, which would sway outside of the organisms ability to tolerate.

What substances keep the pH level in living organisms more or less constant?
buffers :D
