Although copper doesn''t readily react with dilute hydrochloric acid and dilute sulfuric acid (low in reactivity series), if heated with nasty oily concentrated sulfuric acid you make nasty pungent irritating sulphur dioxide gas and white anhydrous copper(II) sulfate, but this is NOT a reaction on which to base its place in the metal reactivity series and hydrogen gas isn''t produced.

Galvanising- Zinc is more reactive than iron, as it is further up the reactivity series. So the zinc will be oxidised instead of the iron. A coating of zinc can be sprayed onto the object. Or big blocks of zinc can be bolted to the iron.

Redox-inert zinc (Zn) is the most abundant metal in the brain and an essential component of numerous proteins involved in biological defense mechanisms against oxidative stress. The depletion of zinc may enhance DNA damage by impairing DNA repair mechanisms.

Iron(II) sulfate - Wikipedia
All the iron(II) sulfates dissolve in water to give the same aquo complex [Fe(H 2 O) 6] 2+, which has octahedral molecular geometry and is paramagnetic. The name copperas dates from times when the copper(II) sulfate was known as blue copperas, and perhaps in analogy, iron(II) and zinc sulfate were known respectively as green and white copperas.

Metals and amyloid-β in Alzheimer''s disease
28/2/2005· Although Cu is the trace metal most strikingly affected in these transgenic and knockout mouse models, other less pronounced metal level changes may have some importance. The Cu deficit in Tg2576 mice was accompanied by a small but significant decrease in Zn levels ( Maynard et al . 2002 ), whereas the Cu increases in APP –/– mice were accompanied by nonsignificant increases in Zn ( …
Reactivity Series Definition in Chemistry
10/2/2020· Metals that do not react in water may react in acid. When metal reactivity is to be directly compared, a single displacement reaction serves the purpose. A metal will displace any metal lower in the series. For example, when an iron nail is placed in a copper
Zinc: uses, appliions-Metalpedia
Zinc: uses Uses of zinc With good calenderability, abrasive resistance, corrosion resistance, castability, and room temperature mechanical properties, zinc can be made into various alloys with many other metals.Mainly in the form of galvanization, zinc-based alloys
GCSE CHEMISTRY - The Reactivity of Metals with Dilute …
The reaction of zinc with sulfuric acid is often used to make a small amount of hydrogen in the laboratory - see moles. The reaction is slow at room temperature but its rate can be increased by the addition of a little copper(II) sulphate. Zinc displaces copper metal.
Reactivity series of Metals
4. Displacement reactions of metals with metal salts A more reactive metal will displace a less reactive metal from a solution of one of its salts. Example: If we dip a zinc strip in copper sulphate solution, copper metal is deposited on the zinc. Zn (s)+ CuSO à
Metals and Non-metals Class 10 Important Questions …
(i) The most reactive metal is E as it displaces Zn from ZnSO 4 solution. (ii) The least reactive metal is C as it cannot displace even Ag from AgNO 3. (iii) If ‘D’ is more reactive than copper, then the brown coating on the metal would be formed.

Solution: Copper is used to make hot water tanks and not steel (an alloy of iron) because copper does not reacts with either water or steam whereas iron reacts with steams to corrode the tank. NCERT Solutions for class 10 Science Chapter 3- Metals and Non-metals
In chemistry, the term ''base metal'' is used informally to refer to a metal that oxidizes or corrodes relatively easily, and reacts variably with dilute hydrochloric acid (HCl) to form hydrogen.Examples include iron, nickel, lead and zinc.Copper is considered a base metal as it oxidizes relatively easily, although it does not react with HCl.
