Sulfuric acid is one of the most widely used industrial chemicals. Because of its importance, sulfuric acid was considered an excellent indicator of a country's industrial wellbeing. Sulfuric acid production closely mirrors historical events affecting the world economy. During periods of or political or economic upheaval production of sulfuric acid dropped, during the First and Second World Wars and the period after

the Second World War there was great economic growth and this was reflected

by ever-increasing sulfuric acid production. Two other chemicals,

caustic soda and ammonia, display the same basic trends.

What happens when you add universal indicator to sulfuric acid?

It turns the universal indicator to scale 1


What does an universal indicator tell you about an acid that litmus doesn't?

Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.


What colour would the red petal indicator be in sulphuric acid?

The red petal indicator would turn blue in sulfuric acid. This color change occurs due to the strong acidity of sulfuric acid causing a shift in the pH level, resulting in the red petal indicator changing color.


What colour should sulfuric acid be after universal indicator is added?

Sulphuric Acid is colourless. When universal indicator (UI) is added, sulphuric acid remains colourless. The universal indicator turns 'RED'. Howver, because the UI is in solution with the sulphuric acid, the solution appears to be red.


What is the significance of sulfuric acid strength in industrial applications?

The strength of sulfuric acid is important in industrial applications because it determines its effectiveness in various processes such as chemical reactions, metal processing, and cleaning. Stronger sulfuric acid can react more quickly and efficiently, making it a valuable tool in industries such as manufacturing, mining, and agriculture.


What is the molarity of concentrated sulfuric acid?

Concentrated sulfuric acid is typically around 18 M in strength.


What happens if sulfuric acid is added in phenolphthalein?

Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.


What indicator will be used in standardization of sulfuric acid against sodium carbonate?

In standardization of sulfuric acid against sodium carbonate, the indicator typically used is phenolphthalein. Phenolphthalein turns pink in basic solutions, which helps in determining the endpoint of the reaction between sulfuric acid and sodium carbonate.


Which indicator would you use in the titration sulphuric acid with naoh?

In the titration of sulfuric acid with sodium hydroxide (NaOH), a pH indicator suitable for a strong acid-strong base titration, such as phenolphthalein, can be used. Phenolphthalein changes color at around pH 8.2-10, which is suitable for detecting the endpoint of the neutralization reaction between sulfuric acid and sodium hydroxide.


What colour is made by mixing bromothymol blue and sulphuric acid?

Mixing bromothymol blue and sulfuric acid would not result in a colour change, as sulfuric acid is a strong acid and bromothymol blue is a pH indicator that changes colour based on the acidity or alkalinity of a solution.

Why 2N sulphuric acid is used in oxalic acid estimation?

This titration is based on the neutralization reaction between oxalic acid and sulfuric acid; a pH indicator is used.
