3. Consider the reaction between 25.00 mL of 0.120 M CH3COOH with 15.00 mL of 0.120 M NaOH.a. How many mmol of CH3COOH are dissolved in 25.00 mL of 0.120 M CH3COOH? b. How many mmol of NaOH are dissolved in 15.00 mL of 0.120 M NaOH? c. The limiting reactant is _________________ while the …
EXPERT ANSWER Initial [Sr2+] = 0.0100 M Initial volume of Sr2+ solution = 50.00 mL Initial milimoles of Sr2+ = 50 * 0.010 = 0.5 mmoles At pH = 11, 4 of EDTA = 0.85 KSrY = 4.3×108 Conditional constant, K’SrY = 4 * KSrY = 0.85 * 4.3×108 = 3.655×108 When 0.0 mL EDTA is added – [Sr2+] = 0.010 M …
EXPERT ANSWER Answer Step 1 Silver nitrate reacts with CN– to form a white precipitate of silver cyanide. Silver nitrate react with I– to form precipitate of AgI. Step 2
EXPERT ANSWER Answer: This is the Iodometric involes indirect titration of iodine liberated by reaction with an analyte,whereas iodometry involes direct titration using iodine as titrant. Redxc titration using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used sphecifically titrate iodine.In this titratio starch is used as indicator since …
EXPERT ANSWER ANSWERS) 1.the more concentrated the substrate is within a solution, the more frequently substrate molecules will randomly collide with the enzyme in the proper orientation for the active site to bind to the substrate, and thus the more often substrate will be converted into product..So in general the rate of an enzyme-catalyzed reaction …
EXPERT ANSWER The addition of catechol, i.e. 1,2-dihydroxybenzene, to test tube A increases the color intensity because of the fact that the two fluorophores (two hydroxy groups, adjacent to each other) present in the catechol increase Enzyme Activity rapidly. The addition of hydroquinone, i.e. 1,4-dihydroxybenzene, to test tube C increases the color intensity because of …
