Define term buffer. what component are required for a solution to be buffer

A buffer is a solution that resists any change in its pH on adding small quantity of a base and acid to it.

The component required for a solution to be a buffer is that acid or base and its salt .

That is for a acidic buffer, component required will be acid and that acid salt with a strong or weak base.

For example: A solution of acetic acid and sodium acetate.

For a basic buffer: Component required will be base and that base salt with a strong or weak acid.

For example: A solution of ammonium hydroxide and ammonium chloride.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.

you did not give any options thus this is the best answer i can give to you with this little information you have given

> they are both natural and not man made

> they can be tracked and predicted by the right tools
