Find out `K_(a)` for `10^(-2)` M HCOOH acid ,having pOH equal to 10

How much water (in L) should be added to 10g CH_(3)COOH to given pOH equal to 11. K_(a)(CH_(3)COOH) = 1.8 xx10^(-5)

Statement-1: 10^(-4) M HCl solution is "more acidic" compared to 1M HCOOH solution. (K_(a)=10^(-3)M) Statement-2: HCl is a strong acid compared to HCOOH.

Find the number of waves in an orbit fo H-atom having radius equal to 8. 464 xx 10^(-10) m .

Specific conductance of 10^(-4)M n -Butyric acid aqueous solution is 1.9 xx 10^(-9)S m^(-1) . If molar conductance of n-Butyric acid at infinite dilution is 380 xx 10^(-4) S m^(2) mol^(-1) , then K_(a) for n-Butyric acid is:

A mixture of weak acid is 0.1M in HCOOH (K_(a) = 1.8 xx 10^(-4)) and 0.1M in HOCN (K_(a) = 3.1 xx 10^(-4)) . Hence, [H_(3)O^(o+)] is

Find out the percentage dissociation of an acid having conc. Of 10 M and dissociation constant 1.0xx10^(-3) .

Given that K_(w) for water is 10^(-13) M^(2) at 62^(@) C, compute the sum of pOH and pH for a neutral aqueous solution at 62^(@) C:

Out of the following salts identify the one which has maximum solubility (in M) : (P) Barium sulphate having K_(sp)=1.1xx10^(-10) (Q) Aluminium phosphate having K_(sp) =6.3xx10^(-19) (R ) Cadmium iodate having K_(sp)=3.2xx10^(-8) (S) Cuprous chloride having K_(sp) =1.2xx10^(-6)
