In this particular article we will learn about hydrobromic acid and the process of preparation of hydrobromic acid. First a brief introduction to hydrobromic acid. Hydrobromic acid is an inorganic acid also known as a mineral acid. It's composed of hydrogen and bromine and is the bromine analogue of the more famous hydrochloric acid. Now hydrogen bromide is actually a gas but when it’s dissolved in water we call it hydrobromic acid. Azeotropic hydrobromic acid has a boiling point of about 124.3 Celsius at atmospheric pressure   and corresponds to a concentration of 47.6%, although variations of a couple of percent aren't uncommon. It can be used for many of the same purposes as hydrochloric acid but because it is generally more expensive it is more often used when bromine or bromide itself is specifically needed. It's mostly used to make organobromine compounds and we ourselves used it this way sometime ago to make bromoalkanes for making grignard reagents....

In this article we'll be discussing the evolution of computing - more specifically, the evolution of the technologies that have brought upon the modern computing era. We will also see the full form of computer. Full form of computer Commonly Operated Machine Particularly Used for Technology Education and Research History of computing Many inventions have taken several centuries to develop into their modern forms and modern inventions are rarely the product of a single inventors efforts. The computer is no different, the bits and pieces of the computer, both hardware and software, have come together over many centuries, with many people and groups each adding a small contribution. We start as early as 3000 BC with the Chinese abacus, how is this related to computing you ask? The abacus was one of the first machines humans had ever created to be used for counting and calculating. Fast forward to 1642 and the abacus evolves into the first mechanical adding m...

OK ka full form kya hain? What is the full form of OK? OK is such acronym or abbreviation of 2 letters, which is used most in the world, but most people who use it , know its use but do not know the full form. In this article we will see about it and about its history. There’s a two-letter word that we hear everywhere. (OK. Okay. OK, are you OK Annie? OK OK OK, OK ladies…) OK might be the most recognizable word on the planet. OK! OK. It’s essential to how we communicate with each other, and even with our technology. (Alexa, turn off the living room light. OK.) You probably use it every day – even if you don’t notice it. But, what does OK actually mean? And where did it come from? Hm. OK. Okay then. OK, thank you. OK actually traces back to a 1830s fad of intentionally misspelling abbreviations. Young “intellectual” types in Boston delighted those “in the know” with butchered coded messages such as KC, or “knuff ced”, KY,“know yuse,” and OW, “oll wright.”. But thank...

Many of you must be wondering what is the full form of India. In this article you will come to know the full form of India and also the history of our country India. I ndependent N ational D emocratic I ntelligent A rea We begin in the early 20th century, when the vast Indian subcontinent is dominated by the British Empire for nearly 150 years. The region is divided into provinces directly administered by the British Empire, and hundreds of princely states indirectly under the British crown, including Jammu and Kashmir to the north. The colony of India enriches the British Empire, including by providing tea, coffee, cotton, and various tax receipts. Portugal and France still control small areas although these are highly dependent on the British colony. While in the 19th century anti-British revolts are quelled, from the early 20th century nationalist movements regain momentum. During the First World War, about one and a half million Indians are drafted in to ...
