Question

O solution. If lemon juice sample was neutralized by itration with NaOH son NaOH for neutralization, what was the 4) A citric acid, HIC6H5O7 in a lemon juice sample was neutral 10.00 mL of lemon juice required 7. ml. 0.221 M N O for cura molarity of the citric acid in the lemon juice? The balanced reaction is 3 NaOH + A,C,H,0,-3 H0 + NaCl,0, 5) Laboratory HCl bench reagents are generally 6,0 M. How would you prepare 7,50 x 10 mL of 0.18 M HCI (include how many mL of water you will need to add 6) Ir0.550 grams of NaCl was dissolved in a total of 250 ml aqueous solution (15 points) a) Calculate the mass/volume % of NaCl in the solution? b) Calculate the mass percent of the solution. The solution density is 0.945 g/mL. c) Calculate the molarity of the NaCl solution.
