Sodium tetrathionate is formed by the oxidation of sodium thiosulfate (Na 2 S 2 O 3), e.g. by the action of iodine: [1] 2 Na 2 S 2 O 3 + I 2 → Na 2 S 4 O 6 + 2 NaI. The reaction is signaled by the decoloration of iodine. This reaction is the basis of iodometric titrations. Other methods include the coupling of sodium bisulfite with disulfur ...
The triiodide ion solution is then titrated against standard thiosulfate solution to give iodide again using starch indicator: I − 3 + 2 e − ⇌ 3 I − (E 0 = +0.54 V) Together with reduction potential of thiosulfate: [1] S 4 O 2− 6 + 2 e − ⇌ 2 S 2 O 2− 3 (E 0 = +0.08 V) The overall reaction is thus: I − 3 + 2 S 2 O 2− 3 → S ...
Copper(I) thiocyanate is a hole conductor, a semiconductor with a wide band gap (3.6 eV, therefore transparent to visible and near infrared light). [11] It is used in photovoltaics in some third-generation cells as a hole transfer layer.
Stabilizers such as dextrose (typically at about 0.04%) and sodium thiosulfate, which prevent potassium iodide from oxidizing and evaporating. These ingredients are not required for potassium iodate, which is commonly used globally for its increased stability, but is not approved by the US FDA.
1% (w/v) sodium deoxycholate; 0.1% (w/v) SDS; 0.15 M NaCl; 0.01 M sodium phosphate, pH 7.2; 2 mM EDTA; 50 mM sodium fluoride (NaF) 0.2 mM fresh sodium orthovanadate (Na 3 VO 4.2H 2 O, it has phosphatase inhibitor function because it mimics phosphate) 100 U/ml protease inhibitor, such as aprotinin

A typical recipe for making 1X TE buffer is: 10 mM Tris, bring to pH 8.0 with HCl; 1 mM EDTA, bring to pH 8.0 with NaOH; TE buffer is also known as T 10 E 1 buffer, which can be read as "T ten E one buffer".
Xylenol orange is an organic reagent, most commonly used as a tetrasodium salt as an indicator for metal titrations.When used for metal titrations, it will appear red in the titrand and become yellow once it reaches its endpoint.
