Difficulty: MediumHeavy Chemicals and Fine Chemicals

Match each industrial chemical listed on the left with its appropriate chemical category and operational production characteristic on the right.

  • Tetraoxosulfate(VI) acid (H2SO4H_2SO_4)Heavy chemical produced continuously in massive tonnage with moderate purity and low unit cost.
  • Paracetamol (Acetaminophen)Fine chemical produced in small batches with high purity for pharmaceutical applications.
  • Sodium hydroxide (NaOHNaOH)Heavy chemical synthesized on a large industrial scale primarily used as a basic alkali raw material.
  • Analytical grade Silver Nitrate (AgNO3AgNO_3)Fine chemical manufactured in limited quantities with strict chemical purity for laboratory quantitative testing.

Answer

Tetraoxosulfate(VI) acid matches heavy chemical produced continuously in massive tonnage; Paracetamol matches fine chemical produced in small batches for pharmaceutical applications; Sodium hydroxide matches heavy chemical synthesized on a large scale as a basic alkali raw material; Analytical grade Silver Nitrate matches fine chemical manufactured in limited quantities with strict purity for laboratory testing.
Heavy chemicals like Tetraoxosulfate(VI) acid and Sodium hydroxide are manufactured on a massive industrial scale through continuous production processes. They serve as fundamental raw materials for other industries and have low to moderate unit costs. Fine chemicals like Paracetamol and Analytical grade Silver Nitrate are produced in small batch quantities, possess high chemical purity standards, command high unit prices, and serve specialized applications such as medicine and scientific research.

Step-by-Step Solution

1
Analyze Tetraoxosulfate(VI) acid (H2SO4H_2SO_4)
H2SO4H_2SO_4 is manufactured worldwide in millions of tonnes via the Contact process. It is a classic heavy chemical with a relatively low cost per unit mass used broadly across chemical manufacturing.
Heavy chemicals are characterized by high volume, continuous production, and widespread raw material utility.
2
Analyze Paracetamol
Paracetamol is a pharmaceutical drug prepared in small, carefully monitored batch processes to guarantee high chemical purity and safety for human consumption.
Pharmaceuticals are classified as fine chemicals due to their high unit value, precise batch manufacturing, and high degree of purity.
3
Analyze Sodium hydroxide (NaOHNaOH)
Sodium hydroxide is produced in vast amounts alongside chlorine gas in the chlor-alkali process, functioning as a primary basic heavy alkali.
Large-scale industrial bases and alkalis produced for general industrial operations are heavy chemicals.
4
Analyze Analytical grade Silver Nitrate (AgNO3AgNO_3)
Analytical reagents are synthesized in small amounts with strict quality specifications (>99.9%>99.9\% purity) for qualitative and quantitative laboratory procedures.
Specialty laboratory reagents sold in high-cost, small-quantity containers fall under fine chemicals.
