  2. Nickel double salts - Wikipedia

    en.wikipedia.org/wiki/Nickel_double_salts

    Nickel is one of the metals that can form Tutton's salts. The singly charged ion can be any of the full range of potassium, rubidium, cesium, ammonium (), or thallium. [1] As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2]

  3. Nickel compounds - Wikipedia

    en.wikipedia.org/wiki/Nickel_compounds

    Nickel ions can act as a cation in salts with many acids, including common oxoacids. Salts of the hexaaqua ion (Ni · 6 H 2 O 2+) are especially well known. Many double salts containing nickel with another cation are known. There are organic acid salts. Nickel can be part of a negatively charged ion (anion) making what is called a nickellate.

  4. Soil test - Wikipedia

    en.wikipedia.org/wiki/Soil_test

    A soil test is a laboratory or in-situ analysis to determine the chemical, physical or biological characteristics of a soil. Possibly the most widely conducted soil tests are those performed to estimate the plant-available concentrations of nutrients in order to provide fertilizer recommendations in agriculture.

  5. Soil resilience - Wikipedia

    en.wikipedia.org/wiki/Soil_resilience

    Soil resistance, a related term refers to the ability of soil to resist changes or the extent to which a soil will recover from any cropping or management change. The term is distinct from Soil resilience as resistance is the inherent capacity to withstand disturbance, while resilience is the capacity to recover after disturbance. [1] [2]

  6. Nickel organic acid salts - Wikipedia

    en.wikipedia.org/wiki/Nickel_organic_acid_salts

    The nickel organic acid salts are organic acid salts of nickel. In many of these the ionised organic acid acts as a ligand. Nickel acetate has the formula (CH 3 COO) 2 Ni·4H 2 O. It has monodentate acetate and hydrogen bonding. A dihydrate also exists. Nickel acetate is used to seal anodised aluminium. [1]

  7. Standard penetration test - Wikipedia

    en.wikipedia.org/wiki/Standard_penetration_test

    The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...

    My go-to method for years has been (for two of us): five large eggs, one large yolk, salt and pepper, and a splash of cream. I cook the whisked eggs in butter, over the lowest heat possible on the ...

  9. Nickel(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Nickel(II)_sulfate

    Aqueous solutions of nickel sulfate react with sodium carbonate to precipitate nickel carbonate, a precursor to nickel-based catalysts and pigments. [6] Addition of ammonium sulfate to concentrated aqueous solutions of nickel sulfate precipitates Ni(NH 4) 2 (SO 4) 2 ·6H 2 O. This blue-coloured solid is analogous to Mohr's salt, Fe(NH 4) 2 (SO ...
