To determine the molarity of an unknown sulfuric acid solution in a titration, a standardized NaOH solution with a molarity of 0.138 M was given. A student used 11.8 mL of the NaOH solution to reach to the end point of the titration with a 25.0 mL sample of the unknown acid solution. What is the molarity of the unknown sulfuric acid solution?
A chemistry student weighs out 0.0570 g of citric acid (H,C,H,0,), a triprotic acid, into a 250. mL volumetric flask and dilutes to the mark with distilled water. He plans to titrate the acid with 0.1900 M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits. O mL x10
A 50.0 mL solution of Mg(OH)2 of unknown concentration is titrated with 0.348 M HCI. The equivalence point (end point) is reached after 62.8 mL of HCI were dispensed into the Mg(OH)2 solution. What is the molarity concentration of the base?
To increase the acidity of soil, you can add peat, which contains a complex acid mixture known as humic acid, a diprotic acid (two acidic protons). The complexity of the humic acid makes it difficult to determine how acidic you are making the soil. You decide to use a titration to get a better measure. If a titration of an unknown sample of humic acid required 3.68 mmols of NaOH, how many mmols of humic acid were present in the unknown sample?
A 4.80 mL sample of an H3PO4 solution of unknown concentration is titrated with a 1.100×10−2 M NaOH solution. A volume of 7.32 mL of the NaOH solution was required to reach the equivalence point. What is the concentration of the unknown H3PO4 solution? Express your answer with the appropriate units.
Calculate the molarity of an NaOH solution from the following titration data. Be sure the answer has the correct amount of significant figures. The chemical equation for this titration is as follows: NaOH + KHP → NaKP + H₂O NaOH buret reading, inital: 15.27 mL NaOH buret reading, final: 8.32 mL Mass of KHP (204.22 g/mol): 1.1592 g
A titration of 25.00 mL of an unknown HCl solution with 0.1550 M NaOH starts at a buret reading of NaOH of 0.33 mL. The phenolphthalein indicator turns light pink in the acid solution over 30 seconds at a buret reading of 24.19 mL. Write the balanced equation for the neutralization reaction. What is the molarity of the HCl solution?
The molar mass of a metal carbonate can be determined by adding an excess of HCl to completely react with the carbonate and then “back –titrating” the excess acid with NaOH. If 20.0 mL of 0.0800 M HCl was added to a 0.1022 g sample of MCO3, the excess HCl required 5.64 mL of 0.1000 M NaOH for neutralization. Find the molar mass of MCO3 and identify M.
An analytical chemist weighs out 0.065 of an unknown monoprotic acid into a 250mL volumetric flask and dilutes to the mark with distilled water.

Calculate the molar mass of the unknown acid. Round your answer to 2
