    Concentrations of HCl on the Rate of Reaction Between HCl and Sodium Thiosulfate Chemistry Lab report Aim: The aim of this experiment is to determine how concentrations of HCl acid affect the rate of reaction when reacted with Sodium Thiosulfate (Na2S2O3). This experiment would require measuring the mass of the reaction over a period of time to be able to determine the rate of the reaction. Safety Precautions: In this experiment‚ SO2 gas is produced from the reaction between Sodium Thiosulfate and HCl‚ and this

    unrefined sodium carbonate‚ soda ash‚ a titration is done using a standardized solution of HCl. Aqueous HCl is a strong acid and therefore almost completely disassociates into H+ and CL-. Therefore‚ when HCl is used in a titration‚ the H+ is the titrant. Carbonate in aqueous solution is able to accept a proton‚ i.e. it acts as a base. When carbonate accepts the H+ a bicarbonate ion is formed. Na2CO3(aq) + HCl(aq)  NaHCO3(aq) + NaCl(aq) This is not the complete reaction for the titration

    chalk is near the top of the ground‚ it often makes chalk hills. Chalk holds water‚ so these chalk hills have a lot of water in them‚ and when the weather is very dry‚ water comes slowly from the chalk. Chalk is mostly formed from the calcareous (CaCO3) skeletons of countless tiny planktonic algaecalled coccoliths. It was laid down in the Upper Cretaceous period. Chalk can write on a chalk Board. Blackboard chalk is not real chalk. It is really gypsum (calcium sulfate)‚ but often people call it

    various elements and compounds in the unknown‚ its true identity can be predicted. Chloride‚ ammonia‚ and cobalt are three examples of percent compositions determined to help narrow the selection of possible unknowns. Titrations using Na2S2O3 and HCl to determine percent cobalt and ammonia‚ respectively‚ are used. Silver nitrate is used to precipitate the chloride ions in the unknown‚ which can be measured to determine the percent composition of chloride in the unknown. The results from these three

    concentration affect the rate of a reaction? In this investigation I will be investigating to see whether the concentration affects the rate of a reaction. To see if the concentration does affect the rate of a reaction I will be reacting various HCL strengths with Na2S2O3 to see if the concentration affects the rate the two substances react. Also in this investigation I will be looking into see if there are any states the substance should be in that would affect the rate of reaction. The

    antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets (Kremil-S) were crushed and weighed to the nearest 0.01 g which was 0.5003 g and 0.5014g. Then‚ transferred into a 250 mL flask and added 50.0 ml 0.1M HCl using an acid burette. Then‚ the
