The acid-base titration curves help to find the pKa‚ Ka‚ and pH at equivalent point. At the beginning pH for HCl is 1.90 which is lower than the 3.28 for acetic acid; thus‚ strong acid (HCl) means lower pH and weak acid (acetic acid) means higher pH. Then at the equivalent point for the titration HCl-NaOH the pH is 7‚ which mans that is neutral‚ in other words there are enough NaOH mmol to neutralize the HCl mmol present; also‚ the solution contains only water and NaCl the salt derived from the titration

The French Revolution Throughout history the french revolution led an extreme impact on the french society even till this day. There were many causes for the french revolution but the 2 things that mostly fed into it were the unfairness of the first and second estate and the crude treatment that the two gave to the third estates. Due to Louise XVI’s absolute monarchy he had complete power over the french government and people making it harder for

In the Babylonian star catalogues dating from at least 1100 BCE‚ what later became known as Corvus was called the Raven (MUL.UGA.MUSHEN). As with more familiar Classical astronomy‚ it was placed sitting on the tail of the Serpent (Greek Hydra). The Babylonian constellation was sacred to Adad‚ the god of rain and storm; in the second Millennium it would have risen just before the autumnal rainy season. John H. Rogers observed that Hydra signified Ningishzida‚ the god of the underworld in the Babylonian

anniversary of the French revolution. At first some French people were very much opposed to the large metal monument‚ and about 300 people signed a petition opposing it. But now it is a large part of Paris‚ and can be seen from many places in the city. The tower is 310 meters‚ and was the world’s tallest building for many years after its construction. The tower was saved from being torn down in 1909 by its antenna that was used for telegraph transmission. It has been used for French radio and then later
