  2. Sulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Sulfuric_acid

    Sulfuric acid is a colorless oily liquid, and has a vapor pressure of <0.001 mmHg at 25 °C and 1 mmHg at 145.8 °C, [16] and 98% sulfuric acid has a vapor pressure of <1 mmHg at 40 °C. [ 17 ] In the solid state, sulfuric acid is a molecular solid that forms monoclinic crystals with nearly trigonal lattice parameters.

  3. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Soil acidification. Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid, such as nitric acid, sulfuric acid, or carbonic acid. It can also be a compound such as aluminium sulfate, which reacts in the soil to release protons.

  4. Ammonium sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfate

    A mixture of ammonia gas and water vapor is introduced into a reactor that contains a saturated solution of ammonium sulfate and about 2% to 4% of free sulfuric acid at 60 °C. Concentrated sulfuric acid is added to keep the solution acidic, and to retain its level of free acid. The heat of reaction keeps reactor temperature at 60 °C. Dry ...

  5. Tall oil - Wikipedia

    en.wikipedia.org/wiki/Tall_oil

    Tall oil, also called liquid rosin or tallol, is a viscous yellow-black odorous liquid obtained as a by-product of the kraft process of wood pulp manufacture when pulping mainly coniferous trees. [1][2] The name originated as an anglicization of the Swedish tallolja ('pine oil'). [3] Tall oil is the third largest chemical by-product in a kraft ...

  6. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. [1] pH is defined as the negative logarithm (base 10) of the activity of hydronium ions (H+.

  7. Cellulosic ethanol - Wikipedia

    en.wikipedia.org/wiki/Cellulosic_ethanol

    These plants used what was called "the American Process" — a one-stage dilute sulfuric acid hydrolysis. Though the yields were half that of the original German process (25 US gallons (95 L) of ethanol per ton versus 50), the throughput of the American process was much higher.

  8. Sulfur dioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_dioxide

    Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S8 + 8 O2 → 8 SO2, ΔH = −297 kJ/mol. To aid combustion, liquified sulfur (140–150 °C (284–302 °F) is sprayed through an atomizing nozzle to generate fine drops of sulfur with a large surface area.

  9. Sulfur - Wikipedia

    en.wikipedia.org/wiki/Sulfur

    Sulfur is an essential component of all living cells. It is the eighth most abundant element in the human body by weight, [100] about equal in abundance to potassium, and slightly greater than sodium and chlorine. [101] A 70 kg (150 lb) human body contains about 140 grams (4.9 oz) of sulfur. [102]
