Roasted Salt-and-Vinegar Potatoes From Cook’s Country | August/September 2012 Share Email Print Shopping list Add to favorites WHY THIS RECIPE WORKS: Cooking small red potatoes in a super-saturated salt solution creates an incredibly creamy‚ well-seasoned potato interior. After the potatoes are par cooked‚ we “smash” them to expose some of the potato flesh‚ brush them with malt vinegar‚ and roast them on a well-oiled sheet pan until the… read more Roasted Salt-and-Vinegar Potatoes Making crispy

Salt and the effect it has on water. Do you like salt? Do you put it on your food to make it taste better? Salt doesn’t just make food taste better; it can change the freezing and boiling point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis

prevent this‚ here are three different ways you can keep your glass vase clean. A Little Salt and Vinegar Vinegar is a very potent acid so you’ll need a little salt to dilute it. Start by making a cleansing solution. Take half a tablespoon of salt and add in just a few drops of white vinegar to turn it into a semi-solid paste. Avoid adding too much vinegar because then it will be too fluid and the vinegar might be too

Every winter road salt is used on sidewalks‚ roads‚ and highways to melt snow and ice. These are to prevent human activates from turning into accidents. When the snow melts the road salt gets dissolved into the melted ice and snow and becomes a formula. This formula sinks into the land (soil mostly) and kills vegetation. The purpose for this exit project experiment is to find out what are the affects of road salt on plants. The reason for doing this lab is to find out what a

Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

The members in our group were Whitney‚ myself‚ and Charlotte. The title of this lab was “reaction types.” The purpose of this lab was to identify the reaction type‚ balance equations‚ and observe the reactions .Our hypothesis was if there was many stations with fire‚ then they’re would be many combustion reactions. The procedure of the first lab was to place a solid piece of magnesium metal in the bottom of the smallest tube. Place this test tube in the test tube holder. Using tongs pick up the
