Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry. It consists of a series of videos about chemical elements and the periodic table , with additional videos on other topics in chemistry and related fields.
[9]: 2–3 Reactions with water and alcohols are also exothermic and release hydrogen gas: [9]: 3 Ba + 2 ROH → Ba(OR) 2 + H 2 ↑ (R is an alkyl group or a hydrogen atom) Barium reacts with ammonia to form the electride [Ba(NH 3) 6](e −) 2, which near room temperature gives the amide Ba(NH 2) 2. [11] The metal is readily attacked by acids.
Coloured flames of methanol solutions of different compounds, burning on cotton wool. From left to right: lithium chloride, strontium chloride, calcium chloride, sodium chloride, barium chloride, trimethyl borate, copper chloride, cesium chloride and potassium chloride. Some common elements and their corresponding colors are:
Barium chloride is an inorganic compound with the formula Ba Cl 2. It is one of the most common water-soluble salts of barium . Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame.
Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. [4] Ba(N 3) 2 + Li 2 SO 4 → 2 LiN 3 + BaSO 4. It can also be used as a source for high purity nitrogen by heating: Ba(N 3) 2 → Ba + 3 N 2. This reaction liberates metallic barium, which is used as a getter in ...
Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates , it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite .
Barium chromate, is a yellow sand like powder with the formula BaCrO 4. It is a known oxidizing agent and produces a green flame when heated, a result of the barium ions. It is a known oxidizing agent and produces a green flame when heated, a result of the barium ions.
Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds.It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods.
