Determine of pH of acid solutions like 0.1m hcl,0.5m hcl,0.025m hcl,0.0125m hcl by using quinhydrone and calomel electrode .compare the values of pH with theoretically calculated values.
pH = -lg [H + ]; 0.1m hcl: pH = 1; 0.5m hcl: pH = 0.3; 0.025m hcl: pH = 1.6; 0.0125m hcl: pH = 1.9.

How will blue and red litmus paper react with neutralisation reactions and why? These are the reactions: HCl+NH3, CH3COOH+NH3, HCl+NaOH, CH3COOH+NaOH.
In this case is important as behaving in a neutralization products in water HCl + NH3 = NH4Cl NH4Cl + H2O = NH4OH (weak base) + HCl (strong acid) so...

A reddish brown metal is heated in the presence of oxygen forms a black compound. on heating the black compound with hydrogen gas , we get back the metal.what are the metal and compound
Reddish brown metal is copper (Cu). When copper is heated in the presence of oxygen, it forms copper(II) oxide (CuO) - the black compound. Copper (II) oxide can be reduced...

Calculate the mole efficiency of NAOH when 4 grams of NaOH is soluble in 90 grams of water.
n(NaOH) = m/M = 4g/40g/mol = 0.1 moln(H2O) = 90g/18g/mol = 5 molThe mole efficiency of NaOH = n(NaOH)/n(total) = 0.1mol/5.1mol = 0.02
