  2. Surface properties of transition metal oxides - Wikipedia

    en.wikipedia.org/wiki/Surface_properties_of...

    The surface of a metal oxide consists of ordered arrays of acid–base centres. The cationic metal centres act as Lewis acid sites while the anionic oxygen centres act as Lewis bases. Surface hydroxyl groups can serve as Brønsted acid or base sites as they can give up or accept a proton. [14] The surface of most metal oxides will be, to some ...

  3. Nitric acid - Wikipedia

    en.wikipedia.org/wiki/Nitric_acid

    The dioxide then disproportionates in water to nitric acid and the nitric oxide feedstock: 3 NO 2 + H 2 O → 2 HNO 3 + NO. The net reaction is maximal oxidation of ammonia: NH 3 + 2 O 2 → HNO 3 + H 2 O. Dissolved nitrogen oxides are either stripped (in the case of white fuming nitric acid) or remain in solution to form red fuming nitric acid.

  4. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  6. Monocryl - Wikipedia

    en.wikipedia.org/wiki/Monocryl

    Monocryl has a low tissue reactivity, maintains high tensile strength, and has a half-life of 7 to 14 days. At 1 week, its in vivo tensile strength is at 50–60% undyed (60–70% dyed), 20–30% undyed (30–40% dyed) at two weeks, and essentially completely hydrolyzed by 91–119 days. [ 3 ]

  7. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    A basic oxide, also called a base anhydride (meaning "base without water"), is usually formed in the reaction of oxygen with metals, especially alkali (group 1) and alkaline earth (group 2) metals. Both of these groups form ionic oxides that dissolve in water to form basic solutions of the corresponding metal hydroxide :

    Lithium oxide (Li 2 O) is the lightest alkali metal oxide and a white solid. It melts at 1570 °C. Sodium oxide (Na 2 O) is a white solid that melts at 1132 °C and decomposes at 1950 °C. It is a component of glass. Potassium oxide (K 2 O) is a pale yellow solid that decomposes at 350 °C. Rubidium oxide (Rb 2 O) is a yellow solid that melts ...
