What is NiS2O3?

What is NiS2O3?

Nickel(II) Thiosulfate. Alias: Nickelous Thiosulfate. Formula: NiS2O3.

What is the name of SnO2?

Tin(IV) oxide

What does pure tin look like?

Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. Pure tin after solidifying keeps a mirror-like appearance similar to most metals. However, in most tin alloys (such as pewter), the metal solidifies with a dull gray color.

Which is more stable SnO or SnO2?

Even though SnO2, the most stable of the phases has been widely studied, SnO has not been investigated to a large extent primarily because of its ease of transformation into SnO2.

Is SnO2 toxic?

Inhalation: May cause irritation of the upper respiratory system. Ingestion: Poor absorption makes it relatively non-toxic.

Why is SnO2 amphoteric?

Explanation. SnO2 reacts with acid as well as the base. So SnO2 is an amphoteric oxide. Amphoteric oxides can be defined as oxides that can behave as an acid and a base to produce salt and water.

Is SnO2 a semiconductor?

Tin dioxide is an inorganic compound with the chemical formula SnO2. It mainly occurs in the mineral cassiterite, and crystallizes with a tetragonal structure. It is a colorless, amphoteric and diamagnetic solid that is usually thought of as an oxygen-deficient n-type semiconductor.

Is SnO2 basic?

Although SnO2 is insoluble in water, it is amphoteric, dissolving in base and acid. “Stannic acid” refers to hydrated tin (IV) oxide, SnO2, which is also called “stannic hydroxide.” Tin oxides dissolve in acids.

Is zno amphoteric?

Zinc oxide is amphoteric because it reacts with both acids and bases to form salts.

Is SnO acidic or basic?

So, SiO2,GeO2, SnOand PbOare acidic, amphoteric, amphoteric, basic respectively.

Is b2o3 acidic or basic?

b2o3 is an anhydride(when reacted with water, it becomes​ boric acid) of boric acid I.e., b(oh)3 or h3bo3. Hence, it is said to be acidic.

Is al2o3 basic or acidic?

Aluminum Oxide Aluminium oxide is amphoteric. It has reactions as both a base and an acid.

Is B2O3 acidic or amphoteric?

b2o3 is acidic as when reacted with water , it becomes boric acid. al2o3 is amphoteric as it reacts with both acids and bases.

Is In2O3 acidic or basic?

In the textbook, on page 428, figure 11.7 recognizes In2O3 as amphoteric. However, in the solutions manual page SG-131, the table at the very top of the page recognizes it as more of a basic compound.

Which are basic oxides?

“Basic oxides” is a compounds word of “Basic” and “oxides”. Sodium oxide, which reacts with water to produce sodium hydroxide. Magnesium oxide, which reacts with hydrochloric acid to form magnesium chloride. Copper(II) oxide, which reacts with nitric acid to form copper nitrate.

Which is most basic oxide?

Hence, it forms a basic oxide. So, we have seen that out of the given oxides, Bi2O3 is the most basic oxide.

Which order is correct B2O3?

B2O3 > CO2 > N2O3 (acidic)

Is P4O10 acidic or basic?

Problem: P4O10 is classified as an acidic oxide because itA. reacts with acids to produce salt B is insoluble in water. C. reacts with water to produce OH-D.

Is li2o amphoteric?

Which is more acidic co2 or no2?

Thus water is least acidic. From left to right of the periodic table the oxides acidic nature increases. Aakash EduTech Pvt.

Is SO2 an acid?

Sulfur dioxide is one of the few common acidic yet reducing gases. It turns moist litmus pink (being acidic), then white (due to its bleaching effect).

Which one is not an acidic oxide I CO2 II SO2 III no2 IV Co?

Answer. CO is not an acidic oxide.

Which of the following is not an acidic?

NaH2​PO2​ is not an acidic salt. It is a basic salt. It is a salt of weak acid H3​PO2​ and strong base NaOH. Hence, the aqueous solution of NaH2​PO2​ is alkaline in nature.

Which is a basic salt?

A basic salt is any salt that hydrolyzes to form a basic solution. Another definition of a basic salt would be a salt that contains amounts of both hydroxide and other anions. White lead is an example. It is basic lead carbonate, or lead carbonate hydroxide.

Is NaH2PO2 an acidic salt?

NaH2PO2 and NaHPO3 are acid salts.

Which one is not acid salt?

Thus, NaH2PO2 is not an acidic salt.
