Titration lab sheet day 2 (alternate)

The titration table for the question is given below.

Explanation:

The equation used for the neutralization reaction is:

where,

are the n-factor, molarity and volume of an acid.

are the n-factor, molarity and volume of base.

Molar ratio is defined as the ratio of the stoichiometric coefficients of of one reactant to the other reactant.

Concentration is the number of moles present in 1 L of solution. Molarity is unit of concentration.

The chemical equation for the reaction of potassium hydroxide and sulfuric acid is given as:

We are given:

Putting values in equation 1, we get:

For acid, the molar ratio will be =

For base, the molar ratio will be =

Concentration of acid = 0.125 moles/L

Concentration of base (KOH) = 0.15 moles/L

The chemical equation for the reaction of sodium hydroxide and hydrogen bromide is given as:

We are given:

Putting values in equation 1, we get:

For acid, the molar ratio will be =

For base, the molar ratio will be =

Concentration of acid (HBr) = 0.25 moles/L

Concentration of base (NaOH) = 0.375 moles/L

The table for titrations is given below.

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 number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
