An aqueous solution of a strong base has a pH of 10. 220 at 25°C then concentration of the base if the base is
(a) LiOH = 1.66×
M
(b) 
= 3.32×M
Calculation ,
For calculation of concentration of the LiOH and first we have to calculate pOH of the solution.
pH + pOH = 14
pOH = 14 - pOH = 14 - 10.22 = 3.78
pOH = -㏒ [ 
]
[ ] = 
= 
= 1.66×
So , concentration of the base LiOH = 1.66×
So , concentration of the base = 1.66× ×2 = 3.32×

Answer:
Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions.
Answer:
The water would act as a base and would produce an undesired product of ethanol (CH3OH) through a dissociation reaction. If doing a titration reaction, it will likely yield inaccurate results.
For hydrogen-like atom electron transition from n=3 to n=5, it would be classified as an absorption of energy. For hydrogen-like atom electron transition from <span>n=3 to n=2, it would be classified as an emission of energy. Hope this helps. Have a nice day.</span>
