Which metal does not produce hydrogen when added to dilute hydrochloric acid?
All of those metals which are located below hydrogen on the activity series will not replace it, and therefore not create hydrogen gas. Those metals would be copper, silver, mercury, platinum, and gold.
What are the uses of sodium?
* Sodium in its metallic form can be used to refine some reactive metals,such as potassium, zirconium from their compounds. * It is used to purify molten metals. * It is used in manufacturing of soaps. * It is added in certain alloys to improve their structure.
Is an element a substance that increase OH- when added to H2O?
Yes, an element can increase the concentration of OH- in water when added. This is because certain elements, such as alkali metals, alkali earth metals, and some transition metals, are capable of forming hydroxide ions when they react with water.
What happens when dilute sulphuric acid is added to zinc granules . Is it an exothermic or an endothermic reaction?
When dilute sulfuric acid is added to zinc granules, a displacement reaction takes place, resulting in the formation of zinc sulfate and hydrogen gas. This reaction is exothermic, which means it releases heat energy.
Why no gas is released when sulphur is added to dilute hcl?
When sulfur is added to dilute hydrochloric acid (HCl), no gas is typically released because sulfur is a non-reactive element and does not readily react with HCl to produce a gas. Sulfur can only react with strong oxidizing agents, such as concentrated nitric acid or hot concentrated sulfuric acid, to release sulfur dioxide gas.
Why are other metals added to stanless steel?
why are other metals added to stainless steel
What substance is added cordial to make it more dilute?
Water
What will happen if dilute hydrochloric acid was added to sandstone?
If dilute hydrochloric acid is added to sandstone, the acid may react with any calcite present in the sandstone, causing it to fizz and release carbon dioxide gas. However, the effect would be limited as sandstone is mainly composed of silica, which is not reactive to hydrochloric acid. Thus, the overall impact on the sandstone would be minimal.
Is sodium very reactive with water?
Sodium is indeed very reactive with water because it is an Alkali metal. These metals have low melting points. Like the sodium, they are soft enough to be cut with a knife. They are highly reactive.
What gas is evolved when dilute nitric acid is added to Zinc?
When dilute nitric acid is added to zinc, the gas evolved is nitrogen dioxide (NO2) along with water and zinc nitrate.
Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
What is percentage purity of sulfuric acid?
It depends on what has been added or how dilute it is.
