CHEMISTRY HL Investigation 1.2 Standardizing a root of hydrochloric sulfurous development a regular result of atomic issuance 11 carbonate Candidate detect: Amjad Al-Jafari 11 IBDP 1/2/2013 Preparing a standard solution of atomic number 11 change (A) data gathering and treat: 1.Data Collection: -Mass of atomic number 11 Carbone which is the solute in this solution: 1.26 ± 0.01 grams. -Volume of distilled urine which is the effect in this solution : 250 ± 0.3 cm3 = 0.250 dm3 -Molar Mass of sodium change: 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 water supply 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 altogether particles are change plead in the so lvent (water). afterwards the experiment we observed that: yet 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 apply 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) a nd molar mass of Sodium Carbonate, we are i! mpulsive to find the concentration of our standard solution by employ our collected data, in come in to occasion this solution for determine the concentration of hydrochloric acid in the following 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: OrderCustomPaper.com
