Early in his life he had a huge interest in English literature and poetry as well as in chemistry and physics. Alfred’s father disliked his interest in poetry and found his son rather introverted. In order to widen Alfred’s horizons his father sent him to different institutions for further training in chemical engineering. During a two-year period he visited Sweden, Germany, France and the United States….
Neutralisation – How much acid is required to neutralise a base
– Neutralisation – How much acid is required to neutralise a base Introduction ============ Neutralisation is the reaction of a base with an acid to form a neutral solution; which contains salt and water. Acid + Base Salt + Water ————————— In my experiment I am trying to find out how much acid it takes to neutralise a base to form a neutral solution. I will use one molar of Nitric Acid as the acid and one molar of Ammonium Hydroxide as the base. So this will be a 1:1 ratio. (Molarity = how many molecules of the acid or alkali per 1000 cm3 (1 litre) of water.) Nitric Acid + Ammonium Hydroxide a Ammonium Nitrate + Water —————————————————–…
The History of Explosives
– As everyone knows, explosives explode; they require activation energy which sets off the explosion. However, many do not know that explosives are categorized into propellants and high explosives. Propellants burn in a rapid but constant fashion and the projectile is under a steady high pressure, while high explosives change in an irregular pattern and produces a shock that is violent and disruptive (Crystal 428). Ever since the first use of gunpowder, explosives have changed from being simple mixtures of elements that could be ignited into something that had become highly destructive, dangerous, and complex….

Pollution Analysis of River Running through a Community
– … Swirl to get a colour change (this is your pH test) ? Pour a small amount of sample one into the clear beaker, and place it alongside your pH paper scale to compare colours and find your pH readings. For better comparison, hold a white sheet of paper behind the scale and beaker for clarity. ? Dispose of the water in the beaker and clean it thoroughly. Repeat the above step for each water sample. ? Record all observations in a table. Variables: Controlled- the amount of water taken for each sample….
