What is a BA definition?
Definition of Bachelor of Arts 1 : the recipient of a bachelor’s degree which usually signifies that the recipient has passed a certain number of courses in the humanities —abbreviation B.A., A.B. became a Bachelor of Arts after only three years of university attendancerequires a year of Latin of the Bachelors of Arts.
WHAT IS A in chemistry ka?
This equilibrium constant is a quantitative measure of the strength of an acid in a solution. Ka is commonly expressed in units of mol/L. HA is an acid which dissociates in the conjugate base of the acid A– and a hydrogen ion that combines with water to form the hydronium ion H3O+.
WHAT IS A in Ka?
An acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution. The dissociation constant is usually written as a quotient of the equilibrium concentrations (in mol/L): Ka=[A−][H+][HA] K a = [ A − ] [ H + ] [ H A ] .
What is the full form of BA?
The full form of BA is Bachelor of Arts.
What does BA mean in India?
a bachelor’s degree in arts and sciences.
What is KA and KB in chemistry?
The acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution while the base dissociation constant (Kb) is a measure of basicity—the base’s general strength. Ka and pKa. Acids are classified as either strong or weak, based on their ionization in water.
What is the definition of an acid or base?
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid.
What is the simple definition of base?
base, in chemistry, any substance that in water solution is slippery to the touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis).
How do you find Ka in chemistry?
As noted above, [H3O+] = 10-pH. Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 – 10-2.4) = 1.8 x 10-5.
What is Ka unit?
kiloannus or kiloannum (ka), a unit of time equal to one thousand (103) years.
