3:21 < Question 8 of 10 You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC3H₂O4, abbreviated KHP) as the primary standard. KHP (molar mass= 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCI. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 31.95 mL of HCI solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCI solution? 1 4 7 +/- 2 5 8 M 3 60 9 O Tap here or pull up for additional resources Submit XU x 100

Discuss your results. 2AGNO3(aq) +Na2CO3(aq) → Ag2CO3(e) + 2NaNo3(aq) B: Calculate the Normality of solutions containing the following with discussing your results:- 1) 8 gm /L of Na2CO3 (when the CO3² reacts with two protons). 2) 9.5 gm /L of K2CR2O7 (the Cr is reduced to Cr*3).
Hydrogen sulfide (H2SH2S) is a common and troublesome pollutant in industrial wastewaters. One way to remove H2SH2S is to treat the water with chlorine, in which case the following reaction occurs: H2S(aq)+Cl2(aq)→S(s)+2H+(aq)+2Cl−(aq)H2S(aq)+Cl2(aq)→S(s)+2H+(aq)+2Cl−(aq) The rate of this reaction is first order in each reactant. The rate constant for the disappearance of H2SH2S at 28 ∘C∘C is 3.5×10−2 M−1s−1 If at a given time the concentration of H2SH2S is 2.2×10−4 M and that of Cl2Cl2 is 0.029 M , what is the rate of formation of Cl−Cl−? Express the rate in molarity per second to two significant figures.

One way to determine the hardness of a water sample is to precipitate the calcium out of solution as a carbonate. The net ionic reaction for this precipitation is: Ca2+(aq) + CO32-(aq) → CaCO3 (s) A 1.00 L sample of water is drawn from a Phoenix, AZ well and 0.534 g of calcium carbonate is recovered using the above reaction. What was the Ca2+ concentration of the original water sample in ppm? Show your work and include units. Hint: ppm stands for parts per million, and in the case of an aqueous solution, this is equivalent to mg/L.
