syrup (referred to as Caliber)2. Beet juice is the by-product in the production molasses for sugar beets.3 The by-product is generally not processed further (depends on manufacturer) and commonly contains minute particles dispersed through-out liquid. As a result‚ beet juice based blends have a greater tendency to clog filters vs. caliber based blends.1 Performance Characteristics: Caliber possesses a significantly better eutectic point than that of beet juice. This translates to a greater melting

Tennessee’s Lemon Law does not cover used vehicles. However‚ there are several other types of laws that can be used to help in the event there is a discovery that you bought used car lemon. First‚ the Federal Trade Commission (FTC) has what’s called the Used Car Rule that requires dealers to provide consumers with a Buyer’s Guide with warranty and information.

between the end point and the equivalence point is that the end point is just an indicator of when the color changes and titration stops. The equivalence point is when the H+ ions are neutralized by OH- ions‚ which occurs when both are used up in the reaction causing the pH to be 7. The molarity of NaOH from the indicator was exactly .500 M‚ but the molarity for the equivalence point from the second derivative was .688 M. This resulted in a range of roughly 27.3%‚ which is way over the 15% error mark
