material in the world. Over the years lead recycling has greatly matured as a result over half of the lead produced and used each year throughout the world has been used before in other products. Today over 80% of the lead is used in the making of lead-acid batteries which are theoretically speaking 100% recyclable. Lead recycling however has one critical problem‚ lead and the many of the by-products produced during the recycling are poisonous. So lead recycling can be broadly divided into to two categories

Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was performed using two acid catalysts‚ 85% phosphoric acid and sulfuric acid. Tests for unsaturation were performed adding drops of bromine in tetrachloride and potassium

del Río‚ a Spanish-born Mexican mineralogist‚ in 1801 [1]. Some sources say Vanadium is soft because it is ductile [1]. Vanadium is harder than most metals and steels [1] It is resistant to corrosion and it is stable against alkalis‚ sulfuric and hydrochloric acids[1]. It is oxidized in air at about 933 K (660 °C‚ 1220 °F) [1]. This paper will discuss the effects of Vanadium on the environment and Vanadium’s properties. Chemical Properties: Vanadium is a transitional metal. Its atomic number

Introduction : Copper(II) sulphate‚ is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid ‚ and copper(II) carbonate ‚ . Through this process‚ the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize

THE IMPORTANCE OF ELECTROLYSIS IN OUR DAILY LIFE “Electrolysis is the passage of an electric current through an electric current through an electrolyte with subsequent migration of positively and negatively charged ions to the negative and positive electrodes. “ 1 Electrodes are metals that are capable to conduct electricity through the solution used in electrolysis. During electrolysis‚ positive and negative electrodes are needed. The positive electrode (anode) experiences oxidation

mimicking the volcano. The volcanic eruption will release quantities of sulfur dioxide and the gas quickly formed tiny droplets of sulfuric acid‚ which acted like minuscule mirrors and reflected some of the sun’s rays back into space. Based on this situation‚ there is one another geoengineering approach to reduce global warming is to mimic the volcanic action by spraying sulfuric acid droplets into the stratosphere. But this approach is not perfect

Vegetative reproduction (vegetative propagation‚ vegetative multiplication‚ vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists. Although most plants normally reproduce sexually‚ many have the ability for vegetative propagation‚ or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic

regain aromaticity. Nitration is defined as replacing a hydrogen with a nitro (NO2) group. Nitration requires the presence of sulfuric acid (H2SO4) as a catalyst. Mechanism of Nitration. A. Overall reaction: B. Mechanism: The nitronium ion is the electrophile generated by the nitric acid/sulfuric acid mixture. The reaction is "sluggish" with nitric acid-sulfuric acid. Note that the reactions are reversible‚ and shifted to the desired products by manipulating concentrations (i.e.‚ adding more
