A31.5 ml aliquot of h2so4 of unknown concentration was titrated with 0.0134 m naoh. it took 23.9 ml of the vase to reach the endpoint of the titration. what was the concentration of the acid

solve for the molarity of H+, which reacts 1:1 withNaOH, using:

M1V1 = M2V2

(M1)(31.5 ml) = (0.0134M)(23,9ml)

M1 = 0.010167 molar H+ ion

since it takes 2 H+ ions to make 1 H2SO4:

0.010167 molar H+ ion => 1/2 as much=> 0.00508 M H2SO4

your answer is 0.00508 M H2SO4

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

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
