Mud filtration test to determine volume of filtrate and the permeability of mud cake collected after a 30-min period of time using filter paper. These tests are the low temperature/low-pressure fluid loss test, often called the American Petroleum Institute (API) test. Questions: 1- When conducting the experiment, why should the pressure be maintained (100 psi)? 2- What are the two most important benefits of mud cake? 3- What kind of log can thickness of mud cake be measured?
Similar to a lab described in class, a small amount of marble chips (CaCO3) are placed inside a flask and weighed (as seen in 1 above). Nitric acid (HNO3) is added with a buret causing a reaction to occur (as seen in 2&3 above). After the reaction ends, the liquid is drained away, the remaining chips rinsed and dried (seen in #4 above). The data collected is as follows: * Mass of flask with chips before reaction: 120.15 g Mass of flask with chips after reaction: 114.09 g Buret reading before acid is added: 45.34 mL Buret reading after acid is added: 22.01 mL Use the above data to determine the molarity of the nitric acid (HNO,) if the equation for the reaction is: 2HNO3(aq) + CaCO,(s) H2O(1) + CO2(g) + Ca(NO,) (ag) (round your final answer to 2 decimal places)
