- d) What mass (g) of sodium hydrogencarbonate would be required to completely neutralise atypical ant sting?arrow_forwarda) Lysine is an essential amino acid. It is taken by some people as a nutritional supplement in the form of a hydrated crystalline solid with the formula C6H₁4N2O2.XH₂O . To control the dose of lysine, it is essential to know the complete formula of the hydrate, which means determining the value of x. To determine the value of x in lysine hydrate, a pharmacist used a direct titration method. She dissolved 6.258g of the compound in approximately 100mL of distilled water and then made this up to 250mL in a volumetric flask. She then titrated 25mL aliquots of this solution with a standardized NaOH solution of concentration 0.1050 mol dm-³, obtaining a mean titre of 36.30 mL. In titrations, lysine behaves as a monoprotic acid. Use these data to determine the value of x in lysine hydrate. b) In a second experiment to verify the value of x, the pharmacist heated a 3.752g sample of the lysine hydrate to drive off all the water. When she reweighed the sample, the mass was 3.278 g. Use this…arrow_forwarddiscuss the practical methods of preparation of naturad dyes, their physical properties and their uses ?arrow_forward
