Hard acids and bases have small, compact structures and tend to form strong, localized bonds. Soft acids and bases have larger, more diffuse structures and form weaker, more delocalized bonds. This difference affects their reactivity and ability to form complexes with other molecules.
Sapphire is a form of corundum, which is a very hard and chemically resistant mineral. It does not react to acids, including strong acids like hydrochloric acid or sulfuric acid. Sapphire is typically only affected by very strong bases or alkalis.
It is difficult to determine the end point of such a titration, because the titration produces a buffer solution that changes its pH very slowly at the end point, in contrast to reaction between a strong acid and strong base.
The rate of temperature change typically depends on the temperature difference between the two beakers according to Newton's Law of Cooling. The greater the temperature difference, the faster the rate of temperature change between the two beakers.
Calcium soap of fatty acids can be made by reacting calcium hydroxide with a mixture of fatty acids derived from oils or fats. This process typically involves heating the fatty acid mixture with calcium hydroxide until a soap is formed. The calcium soap can then be separated and purified for use in various applications.
No, quartz does not fizz in hydrochloric acid. This is because quartz is a hard and resistant mineral that is not reactive to acids.
absolutely nothing
one is hard
what is the defference between cassette tape and hard disk
to hard
It is a difference between the hardness, generally expressed in the Mohs scale.
A hill is hard to get up and a pill is hard to get down
The hard disk is the device that stores the folders.
The difference is in the name; soft corals are soft have body ; with no bony or hard Parts
You can go to sleep with the light on...
a lot
there is no difference just grades and hard work
There's no difference other than what's on them.
