Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

 


Doing an internship at the University of Lille in France, I almost always found myself stuck whenever I had to speak to non-Indians about India or on anything 'Indian'. This was more because of the subtle differences in the way the French understood India in comparison to what I thought was 'Indian'. For instance, when I, or any Indian for that matter, say 'Hindi' is an Indian language, what it means is that it is one of the languages widely spoken in India. This need not be similar to the understanding that the French would have when they hear of 'Hindi' as an Indian language. Because for them Hindi then becomes the only language spoken in India. This is a natural inference that the French, Germans, Italians and many other European nationals would tend to make, because that is generally how it is in their own respective countries. The risk of such inappropriate generalisations made about 'Indian' is not restricted to language alone but also for India's landscape, cuisine, movies, music, climate, economic development and even political ideologies. The magnitude of diversity of one European country can be easily compared to that of one of the Indian State, isn't it? Can they imagine that India is one country whose diversity can be equated to that of the entire European continent? The onus is upon us to go ahead and clarify the nuances in 'Indianness' while we converse. But why should one do so? How does it even matter to clarify?

Q:

Permanent Hardness of water can be removed by adding

A) Bleaching powder B) Chlorine
C) Wasshing soda D) Potassium permanganate
 
Answer & Explanation Answer: C) Wasshing soda

Explanation:

Hardness can be removed by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.

 

Hardness in water is caused by dissolved magnesium ions and calcium ions. These can get into the water when it comes into contact with limestone and other rocks that contain calcium compounds. This can happen, for example, when rainwater flows over these rocks on its way to a reservoir.

 

Hardness in water is of two types. They are :

1. Temporary hardness

2. Permanent hardness

 

1. Temporary hardness:: Temporary hardness is caused by dissolved calcium hydrogen carbonate.


2. Permanent hardness:: Permanent hardness is caused by dissolved calcium sulfate. Unlike temporary hardness, it is not removed by boiling the water.
