and is a strong acid. Where comparing to the conductivity of distilled water to HCL would be evidently HCL. This is because distilled water doesn’t contain ions‚ hence no movement of electrons‚ furthermore no conductivity. However since we added sodium chloride‚ distilled water will have some conductivity but no where near the amount of HCL. Comparing to the conductivity of vinegar to HCL mostly relays on how acidic each other are. Since HCL is a strong acid and vinegar is a weak acid‚ this will impact

was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate was added. For the compound to be confirmed‚ a white precipitate should form again‚ and it did. The next reaction started with the combination of Sodium Sulfate and Ammonia Hydroxide and

Acid Rain Introduction: Titrations are often recorded on graphs called titration curves‚ which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the two solutions). The equivalence point on the graph is where all of the starting solution (usually an acid) has been neutralized by the titrant (usually a base). One can easily find the pKa of the monoprotic acid by finding

Taki Simadiris p1 Brierly Post-lab a. If you did not wash all of the Calcium Carbonate out of the beaker and into the filter during step 5‚ would your percent yield be larger or smaller? If you do not wash all of the Calcium Carbonate out‚ then the percent yield would be smaller because there is enough calcium carbonate left in the beaker that would have attributed to the final yield. b. If you used tap water instead of DI water what do you think would happen? Why? If you used tap water‚ the coffee

Weak Acid Titration Abstract: Our method for determining the unknown weak acid was to determine the equilibrium constant K from the molecular weight of the weak acid from our titration data. In this lab the acid Potassium hydrogen phthalate and two unknown acids were titrated. We determined the molar mass of the Potassium hydrogen phthalate‚ for the unknown acids we calculated the molar mass and the Ka values. We used NaOH as the known base for titrating in all three of the titrations. Our
