Trick.. weak acid, Stronge Acid, Weak Base, Stronge Acid


Trick for S.A. , S.B  & W.A , W.B


STRONG ACID
Remember 7 strong acid...
Out of those, 4 acid are made up of halogen so it is simple
eg. HCl, HBr, HI , HF
For remaining 3 acid, remember the subscipts 2,3,4 eg. H2SO4 , HCLO3, HCLO4
And all types of salt

It works for me

WEAK ACID 
Those acid who don't comes under the 7 names of above strong acid can be considered as weak acid... They includes oxyacids of P and many more

STRONG BASE 
Any soluble salt that contains hydroxide are strong base
ALL ALKALI METAL HYDROXIDE except - Ba(OH)2
Alkali metal = group 1 members

WEAK BASE 
ALL ALKALINE EARTH METAL HYDROXIDE except Ba(OH)2 ,all organic base.
Alkaline earth metals - group -2 members

Buffer Solution

Image
 A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added to it. It is a mixture of a weak acid and its conjugate base, or a weak base and its conjugate acid. Buffer solutions are used in a variety of applications, including:  * Chemical reactions: Buffer solutions are used to maintain a constant pH during chemical reactions.  * Biological systems: Buffer solutions are used to maintain the pH of blood and other bodily fluids.  * Industrial processes: Buffer solutions are used in a variety of industrial processes, such as food production and wastewater treatment. Here are some examples of buffer solutions:  * A mixture of acetic acid and sodium acetate  * A mixture of ammonium chloride and ammonia  * A mixture of citric acid and sodium citrate The pH of a buffer solution can be calculated using the Henderson-Hasselbalch equation: pH = pKa + log([A-]/[HA]) where:  * pKa is the negative logarithm of the ...
