CHEMISTRY HL Investigation 1.2 Standardizing a root of hydrochloric caustic development a type source of atomic snatch 11 carbonate Candidate detect: Amjad Al-Jafari 11 IBDP 1/2/2013 Preparing a standard solution of atomic number 11 carbonate (A) data aggregation and touch on: 1.Data Collection: -Mass of atomic number 11 Carbone which is the solute in this solution: 1.26 ± 0.01 grams. -Volume of distilled pissing which is the effect in this solution : 250 ± 0.3 cm3 = 0.250 dm3 -Molar Mass of sodium carbonate: 2 Na + 1 C + 3 O = 105.99 Observations: beforehand beginning the experiment we notice that: Sodium carbonate is significant powder that has a white colour in, Distilled irrigate is colorless. During the experiment we observed that: As we started to add the solution of Sodium Carbonate to water its particles started to dissolve in the solvent as we are stir until tout ensemble particles are change separate in the solvent (water). afterwards the experiment we observed that: but a white unharmed powder of Sodium Carbonate has been added to water no color change occurred, it stayed colorless, still all particles of Sodium Carbonate has dissolved in water. 2.
Data Processing: Background: We know that a standard solution is a solution with a know concentration, which can be utilise to determine the concentration of solutions with incomprehensible concentration. Today, we are preparing a standard solution of Sodium Carbonate. after(prenominal) collecting our data of the mass of Sodium Carbonate (solute), muckle of water (solvent) and molar mass of Sodium Ca! rbonate, we are impulsive to find the concentration of our standard solution by employ our collected data, in crop to using up this solution for determine the concentration of hydrochloric acid in the bordering part of our investigating (part B). Before calculating the concentration of Sodium Carbonate utilize the following equation: Concentration (mole/dm3) = number of moles (moles) / volume dm3, we should calculate...If you compulsion to get a full essay, order it on our website: BestEssayCheap.com
