Tartaric acid, H, C4H406, has two acidic hydrogens. The acid is often present in wines and
precipitates from solution as the wine ages. A
solution containing an unknown concentration of
the acid is titrated with NaOH. It requires 21.65
mL of 0.3000 M NaOH solution to itrate both
acidic protons in 45.00 mL of the tartaric acid
solution.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

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
