Acid and Base Report Qualitative Data
virulents and Bases Labs Report Aim To study the characteristics of acids and bases. Experiment 1 Magnesium Ribbon with sulfuric Acid Observations Material/substance Rate of answer Bubbles sign comment Final saturation otherwise Observations H2SO4 N/A N/A Colourless N/A Acid Mg N/A N/A Silver Metallic N/A Metal Mg SO4 broad(prenominal) rate Yes- High rate Colourless Colourless Heat is produced. Acidic smell Hydrogen gaseous state was produced. Test Burning Splint Result Popping sound general chemical substance Reaction denomination equality Magnesium + Sulphuric Acid ( Magnesium Sulphate + Hydrogen Chemical comparison Mg + H2SO4 ( Mg SO4 + H2 2. Calcium Carbonate with Hydrochloric Acid Observations Material/substance Rate of reaction Bubbles Initial colour Final colour Other Observations HCL N/A N/A Clear N/A Acid Lime Water N/A N/A Clear N/A N/A Ca CO3 N/A N/A White N/A Salt Ca CO3 + HCL High rate/ fasting Yes.High rate/ Milky, Cloudy White, Cloudy, Heat is produced. Fast shine formed Observation of Final solution Final solution was cloudy with precipitation. Overall Chemical Equations rallying cry Calcium Carbonate + Hydrochloric Acid ( Calcium Chloride + Carbon Dioxide + Water Chemical Equation Ca2CO3 + 2HCL ( 2CaCl + CO2 + water 3. Almost equal amounts of sodium hydroxide and nitric acid (same concentration) Observations Material/substance Rate of reaction Bubbles Initial colour Final colour Other Observations HNO3 N/A N/A N/A N/A NaOH N/A N/A N/A N/A HNO3 + Indicator N/A N/A Strong Pink/ rose criticize/ clear Test with PH paper PH 1, maroon NaOH + Indicator N/A N/A Test with PH paper PH 14, Dark purple HNO3 + NaOH High rate/ Fast N/A Heat is produced.
