- Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the formula KHC8H4O4. This is often written in the short-hand notation as KHP. If 25.0mL of a potassium hydroxide solution are needed to neutralize 2.26g of KHP, what is the molarity of the potassium hydroxide solution? Potassium hydrogen phthalate sometimes called potassium biphthalate, as shown on this bottle is an acid that is convenient to store and use because it is a solid.port youl answers WILH igures.

- You are asked to weigh 2 g of lithium and add it to 1500 ml of distilled water +2drops of indicator, knowing that the density of water is 1 at room temperaturewhile conducting this experiment. After calculating the amount of LiOH, you need to dilute to prepare 0.25 M of LiOH in a 3000 ml solution. Show your calculation and units.Knowing that the initial volume that you used was 1500 ml. Use this equation to calculate ( CLiOH x VLiOH) before dilution = (CLiOH x VLiOH) after dilutionA commercial vinegar is analyzed for the percent acetic acid present. The data for the first trial is given below. Calculate the required quantities using the raw data below. Preparation of Vinegar Sample: • Mass of vinegar (g) = 3.06 Analysis of Vinegar Sample: • Buret reading, initial (mL) = 25.40 • Buret reading, final (mL) = 3.70 • Molar concentration of NaOH solution (mol/L) = 0.0940What is the n-factor (valency factor) of Silver Nitrate (AgNO3)? please also help me with this, thank you so much!
