Sodium selenide reacts with acids to produce toxic hydrogen selenide gas. Filling the burette, measuring out the alkali into the flask, and titrating it until it is neutralised takes about 20 minutes, with false starts being likely for many groups. In order to properly dispose of acids, such as hydrochloric acid (a strong acid), we need to neutralize it by adding a base until its pH is neutral. Sodium Hydroxide Formula, Structure & Symbol | What is NaOH? Information about your use of this website will be shared with Google and other third parties. et al. pH of Common Acids and Bases. The compound reacts with electrophiles to produce the selenium compounds. This can be done by combining the acid with a base, such as sodium hydroxide (a strong base). Sanjana, N. E., Shalem, O. A phenolphthalein indicator served as the bridesmaid for the acid bride. We can evaporate the water off by slowly boiling the solution over a heat source (such as a Bunsen burner), which will leave us with salt crystals. Cancer Discov. Wear proper protective equipment, such as gloves, safety glasses, and lab coat, to protect from splashes before beginning the neutralization process. CAS SEPHS2 is required in cancer cells to detoxify selenide, an intermediate that is formed during selenocysteine biosynthesis.

One such reaction occurs between hydrochloric acid (HCl) and sodium hydroxide (NaOH). But it just so happened that the handsome Sodium Hydroxide, from the Alkali family, fell in love with the enchanting Hydrochloric Acid from the Acidfamily! As sodium selenite, the chronic toxic dose for human beings was described as about 2.4 to 3 milligrams of selenium per day. Olm, E. et al. One of the most widespread alkalis, also known as causticsoda. Reduce the volume of the solution to about half by heating on a pipeclay triangle or ceramic gauze over a low to medium Bunsen burner flame. Its like a teacher waved a magic wand and did the work for me. The solubility of sodium chloride does not change much with temperature, so simply cooling the solution is unlikely to form crystals. Chest 77, 554555 (1980). Counts are from random fields. This hydrolysis occurs because of the extreme basicity of the Se2 ion. Students should be able to: describe how to carry out titrations using strong acids and strong alkalis only (sulfuric, hydrochloric and nitric acids only) to find the reacting volumes accurately. The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods. As a result, when mixed with HCl (acid) it will react to form salt and water, both neutral substances.

Normalized mRNA-Seq expression profile data from patient tumor tissues and normal tissues was obtained from GEPIA (Tang, Z. et al. Hydroxides are strong bases but have low solubility which confines the pH to an upper bound. However, this activity also becomes a liability for cancer cells because selenide is poisonous and must be processed by SEPHS2. It is actually quite simple - you neutralize it by turning it into salt water! Sodium hydroselenide is a chemical compound, an inorganic salt; each unit consists of one sodium, one selenium, and one hydrogen atom.
