Explanation:

Pineapple juice often shows an unstable cloud and produces a solid precipitate that is not very attractive for consumers. Cloud stabilization by pectin addition is permitted by EU and Codex standards to counteract this effect. This additive must be labeled and its content should not exceed fixed maximum standards (Website of AIJN Code of Practice). Determination of water-soluble pectins by IFU method 26 (Website of International Fruit and Vegetable Juice Association) can be used for control of this parameter. Pectin addition to pineapple juice or juice concentrate, etc. may also be detected after its isolation by 13C isotopic analysis (Hammond, 2006) as explained later.

corrected question:

A chemist determined by measurements that 0.03 moles of calcium sulfide participate in a chemical reaction. Calculate the mass of calcium sulfide that participates

Answer:

Explanation:

number of moles of CaS

molar mass of CaS = 40+32 = 72g/mol

number of moles = mass/ molar mass

mass = number of moles * molar mass

mass = 0.03 *72

mass of calcium sulfide = 2.16g

A 45.0 mL sample of 0.020 M acetic acid (HC2H3O2) is titrated with 0.020 M NaOH.? Determine the pH of the solution after adding

White raven [17]

Answer:

Explanation:

CH₃COOH + NaOH = CH₃COONa + H₂O .

.02M

CH₃COOH = CH₃COO⁻ + H⁺

C xC xC

Ka = xC . xC / C = x² C

1.8 x 10⁻⁵ = x² . .02

x² = 9 x 10⁻⁴

x = 3 x 10⁻²

= .03

concentration of H⁺ = xC = .03 . .02

= 6 x 10⁻⁴ M , volume = 45 x 10⁻³ L

moles of H⁺ = 6 X 10⁻⁴ x 45 x 10⁻³

= 270 x 10⁻⁷ moles

= 2.7 x 10⁻⁵ moles

concentration of NaOH = .0200 M , volume = 35 x 10⁻³ L

moles of Na OH = 2 X 10⁻² x 35 x 10⁻³

= 70 x 10⁻⁵ moles

NaOH is a strong base so it will dissociate fully .

there will be neutralisation reaction between the two .

Net NaOH remaining = (70 - 2.7 ) x 10⁻⁵ moles

= 67.3 x 10⁻⁵ moles of NaOH

Total volume = 45 + 35 = 80 x 10⁻³

concentration of NaOH after neutralisation.= 67.3 x 10⁻⁵ / 80 x 10⁻³ moles / L

= 8.4125 x 10⁻³ moles / L

OH⁻ = 8.4125 x 10⁻³

H⁺ = 10⁻¹⁴ / 8.4125 x 10⁻³

= 1.1887 x 10⁻¹²

pH = - log ( 1.1887 x 10⁻¹² )

= 12 - log 1.1887

= 12 - .075

= 11.925 .

Bauxite is the chief ore from which aluminum is extracted. Which of these statements is correct about bauxite?

Eddi Din [679]

Answer : The correct answer is Option D.

Explanation:

Ores are defined as natural occurring substance from which metals and another mineral are extracted.

Bauxite is primary ore of an aluminium metal. it doesn't have definite or specific chemical composition. This is because it contains mixture of hydrous aluminum oxide $Al_2O_3$ , aluminum hydroxides $Al(OH)_3$ , insoluble materials like hematite, quartz ,geothite ,magnetite etc.

From the given options the most appropriate statement which is correct about the bauxite is 'It does not have a definite chemical composition'.

Hence, the correct option Is (D).
