How to Identify Lewis Acids and Bases and Their Conjugate Base Formulas?

AI Thread Summary
Lewis acids are defined as compounds that accept electrons, while Lewis bases are those that donate electrons. To identify conjugate bases, one can derive them from their corresponding acids by removing a proton (H+). For example, the conjugate base of NH3 (ammonia) is NH4+, formed by the gain of an electron. Additionally, a strong acid will have a weak conjugate base, and a strong base will have a weak conjugate acid. Understanding these concepts is essential for identifying Lewis acids and bases effectively.

Whats the formula for this conjugate bases? how do I get them?

a) HSO3tothe(-)
b) NH3
c) HCL

and how is the lewis acid and lewis base identified?

thanks

Read J.D.Lee, elementary questions, pal.
Viloating the Rules I guess, but I will answer.
So Acid are something with donatable H+, which means accepting e-!
That is exactly Lewis Acid, anything that accepts e- is an Acid.
Anything that donates e- is Base!

That is all...

Lewis ACID: Any compound in need of electrons.
Lewis BASE: Any compound that can donate electrons.

Conjugate Concept:
------------------

Suppose you need the conjugate acid of NH3 (Ammonia) which is a base, NH4+ , by gain of electron.

Also A STRONG ACID HAS A WEAK CONJUGATE BASE AND A STRONG BASE HAS A WEAK CONJUGATE ACID.
 
lewis acid/bases interact through dative bonding (the lewis base donates both of the electrons thus it will be the one with the lone pair).
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
