Potassium sorbate,KC H.O, (molar mass 150. g/mol) is commonly added to diet soft drinks as a preservative. A stock solution of KC,H,0,( concentration must be prepared. A student titrates 45.00 mL of the stock solution with 1.25 M HCl(aq) using both an indicator and a pH meter. K for sorbic acid, HC H,O, is 1.7 x 10. a. Write the net-ionic equation for the reaction between KC H,O,(aq) and HCI(aq). b. A total of 29.95 mL of 1.25 M HC\(aq) is required to reach the equivalence point. Calculate the number of moles of H* added. c. Write the equation by which sorbic acid dissolves in water.

To balance the chemical equation SiO2+HF→SiF4+H2OSiO2+HF→SiF4+H2O,you could introduce coefficients a,b,c,da,b,c,d and writeaSiO2+bHF→cSiF4+dH2OaSiO2+bHF→cSiF4+dH2Othen write linear equations for each element.The equation for SiSi would be:   The equation for OO would be:

Qq.52. Subject  :- Chemistry

Describe how you could separate and purify compound A from a mixture of two neutral compounds (A and B) when A comprises 95% of the total and B the other 5% of the total. Assume that A and B have similar polarities.

Define and compare the terms conductive, insulating, and semi-conductive.

Give detailed Solution...don't give Handwritten answer

Nitric acid is used in making flash paper and explosives, and it has a pH of 0.8. Given this information, sulfuric acid is slightly acidic. slightly basic. very basic. very acidic. (Please type answer).

When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A student followed the procedure in this experiment, using 48.92 mL of 1.00 molar HCl and 51.08 mL of 1.00 molar NaOH. Analysis of the collected data resulted in a heat transfer of 2808 J during reaction. Use this information to determine the heat of neutralization for this reaction in kJ/mol. Note: Your answer is assumed to be reduced to the highest power possible.   Your Answer: ___________*10___    Units______
