Is zinc bromide soluble in water?
Water
Is znco3 soluble in water?
Zinc carbonate is soluble in dilute acids, alkalies and in ammonium salt solutions. It is insoluble in water, ammonia, pyridine, alcohol and acetone. Zinc chloride is very soluble in water, and quite soluble in alcohol and acetone. It is also soluble in hydrochloric acid, glycerol and ether.
Which one is more reactive Cu or Zn?
Answer: We find, Zinc is placed higher than Copper in the Electro-chemical Series, since Zinc is more reactive than Copper. Now, the reason is that Zinc loses its valence electrons more easily than Copper to take part in a reaction.
Is Zn more reactive than MG?
In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions ….The reactivity series.
| Element | Reaction with dilute acids |
|---|---|
| Magnesium | Quickly |
| Zinc | More slowly |
| Iron | More slowly than zinc |
| Copper | Very slowly |
What does it mean that an acid is reactive?
Many acids and bases are highly reactive chemicals: they easily combine with other substances in chemical reactions to form new ones. Strong, or concentrated, acids and alkalis are so reactive that they are corrosive: they dissolve substances—including human skin—to cause severe chemical burns.
How do you know if an element is least reactive?
The reactivity of an element can be determined by looking at the electron configuration of the element. The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements.
Which metal is more reactive iron or zinc?
Answer : Zinc is more reactive than iron. Zinc is placed above iron in the reactivity series. For example, Zinc can displace iron from ferrous sulphate solution to form zinc sulphate and iron.
