At what pH is a buffer effective?
buffers help resist change in pH. In our bodies the normal pH is 7.4 which is slightly basic. If for some reason there are excess hydrogen ions in our bodies, the pH will drop and a buffer in the body will counteract this. For example bicarbonate, an important buffer in our bodies, will release bicarbonate ions that will combine with the hydrogen ions forming carbonic acid. Therefore the blood will not decrease in pH.
How you classify the solution as a best buffer solution?
A buffer solution is one involving a weak base/weak acid with its conjugate acid/base. In a buffer solution, the pH must be changed to only a small amount. Thus, any solution with a STRONG acid or a STRONG base is not a successful buffer solution because there would be a relatively large change in the initial pH.
Why did the paper sink in the buffer solution?
The paper sank in the buffer solution because paper is denser than the liquid in the buffer solution. The density of the paper caused it to displace an equal volume of liquid, resulting in the paper sinking rather than floating.
Which buffer system offers the greatest buffer capacity and why?
The buffer system that offers the greatest buffer capacity is one where the concentration of both the weak acid and its conjugate base are equal. This is because the buffer capacity is maximized when there are high concentrations of both the weak acid and its conjugate base, allowing the system to resist large changes in pH by effectively absorbing excess H+ or OH- ions.
Would HF and HCl act as buffers when combined in equal amounts?
No: HCl and HF are both strong acids, and can not buffer each other. A buffer is a combination of a weak acid and a salt of a weak acid.

Any 2 primary colors of light combined in equal amounts produce what?
Any two primary colors of light combined in equal amounts produce a secondary color of light. For example, combining red light and green light in equal amounts produces yellow light.
When combined in equal amounts what color light do these three colors make?
White Light
What is it called if each of the substances of the particles combined are mixed evenly?
A mixture with equal percentage of components.
Which substances will show the smallest change in temperature when equal amounts of energy are absorbed?
Substances with high specific heat capacities, such as water, will show the smallest change in temperature when equal amounts of energy are absorbed. This is because these substances can absorb a lot of heat energy without a significant increase in temperature.
Does 1 IU equal 1 CC?
No. The international unit is different amounts for different substances; it tries to reflect the effect of the substances.
Any two primary colors of light combined in equal amounts produce?
a third color
What does it means to have equal amounts?
An equal amount "matches" each other. So, if you are told to combine milk and water in equal amounts, with the total amount specified as "one cup", the milk would be 1/2 cup and the water 1/2 cup. There are many situations in life where you'll need to know what to do to combine substances in "equal amounts".
When purple and yellow is combined What is the color?
In pigments: Equal amounts of red and blue are used to make purple. Mixing equal amounts of red, blue, and yellow (the three primary colors) will yield brown. In light: Equal amounts of red and blue make magenta (a lighter, more reddish shade of purple). Equal amounts of magenta and yellow make white.
When combined in equal amounts what do the three primary colors of light amounts?
White color is produced when all three primary colors are mixed in equal amount. White color is seen when the three primary colors are reflected equally towards our eyes.
