    Recently, India has launched numerous technological, educational and space missions firmly establishing itself in the international space arena.

    The people of India celebrated in “space exploration” through the ‘Chandrayaan-3 mission (2023)’, wherein India became the first nation to land at or near the south pole of the Moon. The ‘Aditya-L1 mission,’ also launched in 2023, the first Indian solar observing satellite, exhibit it as a entrant to high-level heliophysics. Before that the ‘Mars Orbiter Mission (Mangalyaan) let India become that first country which successfully attained the Mars orbit on its very first attempt. Gaganyaan the program sends the Indian astronauts to space; that do make the entire human race flight space led by India. In ‘technology’, ‘Digital India Initiative’ has changed the face of our nation and UPI is now globally known as Unified Payments Interface. India is also coming up as a popular center for ‘artificial intelligence’ and ‘startups’ where solutions are being developed and implemented in healthcare, agriculture and education sectors. The successful 5G rollout (2022) and programs such as the Semiconductor Mission are evident of India’s push toward technological independence.

    Education’ experienced change through ‘National Education Policy (NEP) 2020’, that aimed at experience based interdisciplinary and technology integrated learning. The IITs & IISc remain among the world’s top rank while the ‘edtech sector,’ with ‘neobrain’ Byju & ‘school learning startup’ Unacademy, scale coverage for students. Education under training program of ‘Gaganyaan’ has taken a step further in teaching space science to students.

    These accomplishments bring to a close and endorse the dominance of India as it rises to exert increasing influence on the future of this world theatre.

    How is Ammonia Prepared in the Laboratory?

    Ammonia is a gas that can be prepared in the laboratory using simple materials and procedures. One common method involves heating ammonium chloride (NH₄Cl) with calcium hydroxide (Ca(OH)₂). Here’s a step-by-step guide:

    Materials Needed:

    1. Ammonium chloride (NH₄Cl)
    2. Calcium hydroxide (Ca(OH)₂) – also known as slaked lime
    3. Test tube or boiling tube
    4. Bunsen burner or a heating source
    5. Delivery tube
    6. Gas jar or collecting bottle
    7. Water trough
    8. Clamp stand and holder

    Steps to Prepare Ammonia:

    1. Set Up the Apparatus:
      • Fix the test tube or boiling tube in the clamp stand.
      • Connect a delivery tube to the test tube. The other end of the delivery tube should be placed in an inverted gas jar or collecting bottle over a water trough.
    2. Mix the Chemicals:
      • Add a small amount of ammonium chloride (NH₄Cl) into the test tube.
      • Add an equal amount of calcium hydroxide (Ca(OH)₂) to the test tube.
    3. Heating the Mixture:
      • Heat the test tube gently using a Bunsen burner. Be careful to heat it evenly and avoid direct, intense heat to prevent cracking of the tube.
    4. Chemical Reaction:
      • When you heat the mixture, a chemical reaction occurs: 2NH4Cl+Ca(OH)2→2NH3+CaCl2+2H2O2 \text{NH}_4\text{Cl} + \text{Ca(OH)}_2 \rightarrow 2 \text{NH}_3 + \text{CaCl}_2 + 2 \text{H}_2\text{O}2NH4​Cl+Ca(OH)2​→2NH3​+CaCl2​+2H2​O
      • In simple terms, ammonium chloride reacts with calcium hydroxide to produce ammonia gas, calcium chloride, and water.
    5. Collecting Ammonia Gas:
      • As the reaction proceeds, ammonia gas (NH₃) is released.
      • The gas travels through the delivery tube and can be collected by displacing water in the gas jar. This method works because ammonia is less dense than water and will rise to fill the jar.
    6. Observations:
      • You will notice a pungent smell, which is characteristic of ammonia.
      • Ammonia gas is colorless and highly soluble in water, so you need to collect it quickly.

    Safety Precautions:

    • Always conduct this experiment in a well-ventilated area or under a fume hood to avoid inhaling the gas.
    • Handle the chemicals with care and use safety goggles and gloves.

    Satyendra Nath Bose made significant contributions to theoretical physics, particularly in quantum mechanics. His most notable achievement is the development of “Bose-Einstein statistics”. In 1924, Bose sent a paper to Albert Einstein describing a novel way to count the states of identical particles, leading to the concept of Bose-Einstein condensates. Recognizing the importance of Bose’s work, Einstein extended it to atoms, predicting a new state of matter.

     

    The particle named after Satyendra Nath Bose is the “boson“. Bosons are particles that follow Bose-Einstein statistics and include particles such as photons and the Higgs boson. Bosons are characterized by having integer spin and can occupy the same quantum state, enabling phenomena like superfluidity and superconductivity.

    E-waste, or electronic waste, poses significant environmental threats. The improper disposal of e-waste leads to the release of hazardous substances such as lead, mercury, cadmium, and brominated flame retardants into the environment. These toxins can leach into soil and water, contaminating ecosystems and posing health risks to humans and wildlife. Additionally, e-waste contributes to air pollution when incinerated, releasing harmful dioxins and furans.

    The environmental impact extends to resource depletion, as valuable materials like gold, silver, and rare earth elements are often lost when electronics are discarded rather than recycled. The extraction of these materials from natural resources is energy-intensive and environmentally damaging.

    Mitigating the impact of e-waste requires a multi-faceted approach. Promoting the recycling and proper disposal of electronics is crucial. Governments and organizations can implement and enforce stringent e-waste regulations, ensuring that manufacturers take responsibility for the entire lifecycle of their products. This can be supported by developing efficient e-waste recycling infrastructure and encouraging the public to participate in recycling programs.

    Furthermore, adopting a circular economy model can reduce e-waste generation. This involves designing products for longevity, repairability, and recyclability, and fostering a market for refurbished electronics. Public awareness campaigns can also educate consumers on the environmental impact of e-waste and the importance of responsible disposal practices.
