50.0 mL of 0.250 M sodium hydroxide at 19.5 oC was added to 50.0 mL of 0.250M hydrochloric acid also at 19.5 oC in a calorimeter. After mixing the solution temperature rises to 21.21oC. What is the heat of reaction? How do you determine the density of this problem? And how do you solve it?
Describe how to make 2.0L of a 2.00 M solution of sodium carbonate from solid sodium carbonate(s). b. Describe how you can make a buffer with sodium carbonate(s) by adding hydrochloric acid. c. How many mL of 1.00 M HCl(aq) are needed to be added to 10.00 g of sodium carbonate to make a buffer at pH =10.00. Ka of HCO3- is 4.7 x 10-11.
Sodium carbonate (MM=105.988 g/mol) is a primary standard base that reacts with hydrochloric acid as follows: Na2CO3 + 2HCI → 2NaCl + H2O + CO2(g) If 39.09 mL of an HCl solution were required to titrate a solution containing 287.5 mg of primary standard Na2CO3, calculate the molarity of the HCl solution.
What is the molar solubility of manganese (II) carbonate in a solution of 0.250M sodium carbonate? Would the molar solubility be greater or smaller is no sodium carbonate was added? Ksp=2.34*10**-11 Please explain!
Sodium carbonate, Na2COs, reacts with hydrochloric acid, HCl, to produce sodium chloride, carbon dioxide and water. Refer to slide 7.18 for a summary of formulae relevant to the calculations below. 2HCI(aq) Na,cO3(aq) NaCl(aq) H2O(I) CO2(g) 1. Use this reaction to explain what is meant by the terms "acid", "conjugate base" and "salt". (6 marks) 2 Balance the equation for this reaction. (2 marks) A solution was prepared by dissolving 5.00 g of Na,CO3 in water and adding water to give...
Describe how you can make a buffer with sodium carbonate by adding hydrochloric acid. Please feel free to be descriptive as possible, I'm learning most of this subject on my own.
thank you
In the lecture we used titration of sodium carbonate with hydrochloric acid as an example to explain how to titrate a weak base with a strong acid. Suppose that you are using HNO3 to titrate Na3PO4, describe how to calculate pH at following different titration stages: (a) before titration (b) at 19 equivalence point (c) at 3rd equivalence point (d) between 2nd and 3rd equivalence points (e) after 3rd equivalence point Calculation is not required, simply write the...
4. Carbon dioxide can be generated by the reaction of hydrochloric acid with calcium carbonate. How many milliliters of dry CO, at 20.0 °C and 755 torr can be prepared from a mixture of 32.1 g of Caco, and 203 mL of 0.245 M HCI?
Write a balanced equation for the reaction of anhydrous sodium carbonate and hydrochloric acid, and a balanced equation for the dehydration of sodium carbonate.
Aqueous sodium hydroxide will react with aqueous hydrochloric acid in an acid-base reaction with a ΔHrxn0 of -55.84 kJ/mole. If 25.0 mL of a 2.15 M hydrochloric solution is mixed with 25.0 mL of a 2.00 M sodium hydroxide solution (both solutions at 23.4 ºC initially), what will be the temperature of the solution when the reaction is over? Assume that the specific heat of all solutions is 4.184 J·g-1·°C-1, and that the density of all solutions is 1.00 g/cm3.
