what is the molarity of an hcl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400 m naoh? group of answer choices 0.200 m 0.280 m 0.320 m 0.500 m

i think its 5049.

i hope this !

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

the answer is symmetrical : )
