Moles of HCl = (50 / 1000) * 0.5 = 0.025 moles
So, moles of CaCO? used = 0.025 / 2 = 0.0125 moles = 1.25 g
95% (Total mass of CaCO? ) = 1.25 g
Total mass of CaCO? = 1.25 / 0.95 = 1.32 g

pH = pK? + log ( [CH? COONa] / [CH? COOH])
pH = 4.57 + log (0.1 / 0.01) = 5.57

Sucralose: Artificial sweetener

Glyceryl ester of stearic acid: The document incorrectly identifies this as "Sodium stearate which is synthetic detergent". Sodium stearate is a soap, not a synthetic detergent.

Sodium benzoate: Food preservative

Bithionol: Antiseptic

For the coagulation of a negative sol, the species Ba²? has the highest flocculating power (referring to the Hardy-Schulze rule, where higher charge leads to greater coagulation power).

For the weak acid HA in the presence of strong acid HCl:
Ka = [ (Cα + 0.1) * Cα] / [C (1-α)] ≈ (0.1 * 10? ²α) / 10? ² = 0.1α
Given Ka = 2 * 10?
2 * 10? = 10? ¹ * α
α = 2 * 10?
Ans = 2

In endothermic reaction formation of reactants is favoured upon decrease in temperature. Addition of inert gas at constant volume and temperature has no effect on equilibrium.
