I WILL GIVE YOU BRAINLIEST An aqueous solution of sodium hydroxide (NaOH) was standardized (the concentration was determined) by titrating it with 25 mL of 0.10 M sample of potassium hydrogen phthalate (KHP). (The equation for this reaction is KHP + NaOH β NAKP + H2O. At the equivalence point of the titration, 32.34 mL of NaOH had been added. Determine the concentration of the NaOH. Show your work.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 β 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 β 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100β°c, how much steam at 100β°c is produced? show all calculations leading to an answer. 10. the freezing of water at 0β°c can be represented as follows: h2o (l) β h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 β 4 sentences explain why applying pressure causes ice to melt.
