What happens when Sulphuric acid react with sodium hydroxide?
When sodium hydroxide react with sulphuric acid they form Sodium sulphate and water. The reactants is base and an acid, which leads to neutralization process and yields a salt .
Which indicator must be used for the reaction between NaOH and H2SO4?
The indicator dye used in this experiment is call “bromothymol blue”. Add 3 or 4 drops of bromothymol blue to the acid solution in the 250 mL beaker. The indicator should turn yellow in the acid solution.
What is observed when sodium hydroxide is added to hydrochloric acid and phenolphthalein?
On adding nearly 5 mL sodium hydroxide solution to the mixture of hydrochloric acid and phenolphthalein solution, the colour of the mixture changes to pink. On addition of hydrochloric acid solution to the pink solution, the colour starts fading gradually and finally the solution becomes colourless.
What happens when sodium peroxide reacts with sulphuric acid?
sodium sulphate, hydrogen and oxygen.
Why do we need to use indicator during titration?
The role of indicator in titration is to detect the endpoint of the titration. When the colour of the solution changes, it indicates that the concentration of the chemical specie has reached a critical range. This change in colour is possible with the help of indicators.
What do you observe when caustic soda solution is added to the hydrochloric acid?
(i) A reddish brown ppt. of ferric hydroxide is obtained which is insoluble in excess of caustic soda solution. (ii) A gelatinous white ppt. of aluminium hydroxide is obtained which is soluble in excess of caustic soda solution.
What can visually impaired students identify acidic and basic solutions?
For visually impaired students, we need an Olfactory indicator . Which smells different in acids and bases. Vanilla essence can be used as an acid-base indicator by visually impaired students as it is an olfactory indicator whose odour changes in acidic or basic media.
When barium peroxide treated with dil h2so4 the products are?
When barium peroxide ( BaO2. 8H2O) is treated with cold and dilute sulphuric acid then we get hydrogen peroxide(HO).
What does 30 volume hydrogen peroxide mean?
30 volume hydrogen peroxide means, 1 ml of hydrogen peroxide solution liberates 30 ml of oxygen gas at STP.
How do you make h2so4 formula?
H₂SO₄
