Cupcakes baked with baking soda as a raising agent. Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3.
The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above. However, solutions of NaOH can be easily supercooled by many degrees, which ...
In Vietnam they are called Tai Dón or Thái Trắng and are included in the group of the Tái peoples, together with the Thái Đen ("Black Tai"), Thái Đỏ ("Red Tai"), Phu Thai, Tày Thanh and Thái Hàng Tổng. The group of the Tái people is the third largest of the fifty-four ethnic groups recognized by the Vietnamese government.
Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates.All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.
Sodium azide is an ionic solid.Two crystalline forms are known, rhombohedral and hexagonal. [1] [6] Both adopt layered structures.The azide anion is very similar in each form, being centrosymmetric with N–N distances of 1.18 Å.
In Vietnam, the Thái nomenclature is composed of several Tai groups, of which the main groups are the Black Tai (Tai Dam, Thái Đen), White Tai (Tai Don, Thái Trắng) and the Red Tai (Tai Daeng, Thái Đỏ). The Tai Lue people are officially classified as a separated group, called Lự.
Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3] is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2.It is structurally similar to urea (H 2 N−C(=O)−NH 2), with the oxygen atom replaced by sulfur atom (as implied by the thio-prefix).
3 I 2 + 6 NaOH → NaIO 3 + 5 NaI + 3 H 2 O. Reactions. Sodium iodate can be oxidized to sodium periodate in water solutions by hypochlorites or other strong ...
