investigate the effect that emersion in salt solutions has on imbibition in kidney beans. * Safety Considerations: * One must use extreme caution when working with chemicals. Always wear protective goggles and gloves when handling them. KCl is slightly hazardous in case of skin contact‚ eye contact‚ ingestion‚ or inhalation. In case of eye contact‚ immediately flush eyes with plenty of water for at least 15 minutes. Seek medical attention if irritation develops. In case of skin contact

based on the steps provided in ‘An Introduction to Chemical Systems in the Laboratory’1. Specifically‚ 1.90 grams of KCL was weighed in a 250ml beaker and dissolved in 25 ml of deionized water. This solution was then quantitatively transferred to a 250ml volumetric flask. Proper technique is needed for quantitative analysis. This transfer was done to ensure that there was no detectable KCl left in the beaker. After transferring the solution add 3 drops of AgNO3 to the rinsed beaked to check the completeness

In nodal analysis‚ the voltage at the reference node is assumed to be zero. The voltages at other nodes are expressed with reference to the datum node. Since the unknown node voltages are determined by nodal analysis‚ it is logical to write the KCL equations at nodes. The procedure can be summarized as follows. ! ! ! ! Select a reference node and treat it to
