Question

What happens when -----

a) magnesium hydroxide reacts with sulphuric acid

b) potassium metals react with the nitric acid.

Answer 1

GOOD NIGHT
HEY BUDDY HERE IS UR


A)Hence the hot water, this reaction is very exothermic and violent. Carbonic acid is produced but instantly decomposes into water and carbon dioxide so a lot of bubbling will occur. ... In my opinion, when magnesium ( Mg) react with sulphuric acid ( H2SO4) . They form Magnesium sulphate ( MgSO4) salt and Hydrogen (H2) gas.



2)A very small piece of potassium metal reacts with nitric acid. If you look closely, it seems that the reaction is less reactive than the same reaction of sodium metal with nitric acid. ... You can see the emission flame of thereaction burning a violet color.

Answer 2

Hey Dear.


Here your answer ⬇⬇⬇

a) Neutralisation reaction is the reaction between an acid and a base, which then yields salt and water. In this reaction, magnesium hydroxide, which is a base, reacts with sulfuric acid to form magnesium sulphate, which is a salt, and two molecules of H20.

b) When potassium metal reacts with dilute sulphuric acid, potassium sulphate and hydrogen gas are formed. Sodium and potassium metal react with dilute acid vigorously. This reaction is highly exothermic.



Hope helped you :)
