| An acid is a chemical substance any of various typically water soluble and sour compounds that are capable of reacting with a base to for a salt‚ that redden litmus paper‚ that evolve hydrogen on reaction with various metals‚ that in water solution yield hydrogen ions‚ and that have hydrogen containing molecules or ions able to give up a proton to a base or that are substances able to accept and unshared pair of electrons from a base. An alkaline is a chemical compound that neutralizes or effervesces

KINETIC STUDY OF LIQUID-PHASE ADSORPTIVE REMOVAL OF HEAVY METAL IONS BY ALMOND TREE (TERMINALIA CATAPPA L.) LEAVES WASTE ABSTRACT. The kinetic sorption of five metal ions - Al3+‚ Cr6*‚ Zn2+‚ Ag+ and Mn2+ - from aqueous solution onto almond tree leaves (ATL) waste in single component system has been studied. The experimental data was analyzed in terms of intraparticle diffusion and rate of adsorption‚ thus comparing transport mechanism and chemical sorption processes. The sorption rates based on

found that‚ in acidic pH environment‚ the reaction rate of starch being broken down by alpha amylase is less than that of the reaction rate at a neutral and slightly basic pH environment. This finding partially supports our hypothesis. The spectrophotometer readings in our experiment measured the absorbance of 3-amino-5-nitrosalicylic acid‚ a colored molecule formed after dinitrosalicylic acid (DNSA) has reacted with the products of the enzymatic reaction or the simple sugars. Therefore‚ the absorbance

Is there really such a thing as rain with acid in it? Yes‚ acid rain is a very real phenomenon worldwide‚ and it’s been documented since the 1800s‚ as the Industrial Revolution caused the burning of fossil fuels like coal‚ gas and oil. When these fuels or any other organic material like wood or paper are burned‚ they release compounds like sulfur dioxide (SO2) and nitrous oxides (NOx) into the air. Are SO2 and NOx the causes of acid rain? Indirectly‚ yes. When SO2 and NOx enter the atmosphere

Heavy Metal Music Good morning to our lecturer and my fellow friends. Today‚ I’m going to inform you about my favourite music genre‚ the heavy metal or metal. I’ll talk about its origin‚ characteristics and its evolvement. I am pretty sure that all of you are not fans of heavy metal. Perhaps‚ some of you did not even heard of it. Heavy metal ‚ often referred to as metal ‚ is a genre of rock music that developed in the late 1960s and early 1970s with roots in blues rock and psychedelic rock. Heavy

is a list of metals arranged in order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them

Determine the Activation Energy of the Reaction between Br— and BrO3— in Acid Solution S.6 ( ) Name: [ ] ( ) Time allowed: 55 minutes Introduction: The reaction can be represented by 5Br—(aq) + BrO3—(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(l) The progress of the reaction may be followed by adding a fixed amount of phenol together with some methyl red indicator. The bromine produced during the reaction reacts very rapidly with phenol. Once
