What else can I help you with?
If 25.0 ml of 1.48m h2so4 can be neutralized with 27.29 ml of koh what is the molarity of the koh?
25 milliliters of the solution has . 037 moles of H2SO4. The neutralization reaction is H2SO4 + 2 KOH yields 2 H2O + K2SO4. So, . 074 moles of KOH are required. This equals 2. 71 mL of solution.
1.122 g of an unknown monoprotic base dissolved in 50.0 mL of water is titrated to endpoint with 20.0 mL of a 1.00 M HCL solution?
Using the mass of the base and volume of the acid, you can calculate the molarity of the base. Then, using the volume of acid required to reach the endpoint, you can calculate the molarity of the acid. Finally, use the stoichiometry between the base and acid to determine the molar mass of the unknown base.
What is the molarity of an unknown acid if 40.5 ml of the acid can be titrated to an end point by 20.5 ml of .2250 M NaOH?
The molarity of the unknown acid can be calculated using the formula: M acid x V acid = M base x V base. In this case, the molarity of the unknown acid is 0.112 M.
Determination the concentration of concentrated hydrochloric acid?
To determine the concentration of concentrated hydrochloric acid, you can perform a titration with a standardized solution of a base, such as sodium hydroxide. By carefully adding the base to the acid solution and monitoring the pH change using a pH indicator or a pH meter, you can identify the equivalence point and calculate the concentration of the acid using the volume and molarity of the base solution used in the titration.
Why you use titration?
Titration is used to determine the concentration of a solution by reacting it with a solution of known concentration. It is commonly used in chemistry labs to accurately measure the amount of a substance in a sample. Titration is a precise and reliable method that allows for quantitative analysis of various compounds.

If you were given the molarity and volume of the acid and the volume of the base what additional step is needed to calculate the molarity of the base?
To calculate the molarity of the base, you would use the formula for dilution: M1V1 = M2V2, where M1 is the molarity of the acid, V1 is the volume of the acid, M2 is the molarity of the base (what you're solving for), and V2 is the volume of the base. Rearrange the formula to solve for M2, the molarity of the base.

What does pH of a solution depend on?
The molarity. The hydrogen ion concentration. If given the Ka just use the Henderson-Hasselbach equation pH=pKa+log(base/acid)

What is the pH of solution with 100 ml 0.2 molarity hydrochloric acid with 0.25 molarity sodium hydroxide at the equivalence point?
Strong acid with strong base always ends with neutral water and the resulting ions Na+ and Cl-, both neutral as well!
Calculating molarity and factor of HCl and Borax solutions in standidization?
To calculate the molarity of HCl solution, you would first titrate it against a known concentration of a base (e.g., NaOH) and use the stoichiometry of the reaction to determine the molarity of the HCl. The factor for the HCl solution would be the ratio between the molarity determined experimentally and the intended molarity. For the borax solution, you would titrate it against a standardized HCl solution to determine its molarity. The factor for the borax solution would similarly be the ratio of the experimental molarity to the intended molarity of the borax solution.
How do we measure the amount of acid or base present in materials?
Measuring pH the acidity or alkalinity of a solution are evaluated.
How do you dilute 30 mL of 12 molar hydrochloric acid to a 0.1 molar hydrochloric acid solution?
in order to dilute the acid, you need to have a good pH meter, a burette, ring stand, burette clamp, and base you want to use. You use the formula Ma * Va = Mb * Vb where Ma is molarity of H+, Va is volume of acid, Mb is Molarity of base and Vb is volume of base. you use that formula to calculate amount of base needed to reach 0.1 molar. to get it exactly right, use a burette and do titration
