we did an experiment in our chem lab wherein we added grinded soda-lime and blended mongo and then heated it. We put moistened litmus paper at a tip of a stirring rod and it turned blue. The questions on our manual are confusing and i'm really having a hard time i need your help... these are the questions:1. What is the role of soda-lime in the reaction?2. Write the chemical equations involved in:a) reaction with soda-limeb) reaction with litmus papers3. why is the soda-lime test NOT considered a confirmatory test for the presence of nitrogen?please.. i need infos.. i'm really confused.. gt;.lt;thanks!^_T kc
Since you mentioned that it's fresh lime juice, you imply that at some point, you had fresh limes. Your best bet would be/would have been to keep the limes intact, and juice them as needed. Since you're apparently dealing with juice: if you store it in a non-reactive container (glass, ceramic or plastic), with a tight lid or seal, it should keep in the fridge for a few months, easily. It's highly acidic, and that inhibits bacterial growth. To store it even longer, just freeze it. A standard ice cube tray holds about one tablespoon per section. Just freeze the lime juice (overnight would be perfect), then put the frozen lime juice cubes into zip-top bags, and store them in the freezer...they'll last for a year or two. Any time you need lime juice for anything, you already know the exact measurement of each cube.
i do no longer think of you are able to. considering sparkling lemon juice has no preservatives, there is not any longer something in it to maintain it from going undesirable. only save it interior the refrigerator, and it is going to final for a minimum of a week. If I have been you, i'd only save the lemons finished and purely squeeze them real once you prefer them. Or there is often bottled lemon juice, which lasts longer and tastes only advantageous.
