(Small amount of salt permits electricity) – Fully ionized as Sodium Chloride Soya Sauce + Water + 2 Electrodes = Strong Light(A lot of sodium in Soya Sauce)V8 Juice + Water + 2 Electrodes = Strong Light(Not as strong as Soya, but still strong – Fair bit of salt in V8 Drink) Na= 11 electronsCl =17 electrons12
**This conducts electricity (Transfer of electrons)**
**Electrolytes enhance electricity in a solution – presence of salts in the products**Activity 3: IonsQuestion 1What did Dr. Harpp mean when he said “ions are charged species”? What best defines ions.Answer: An ion is an electrically charged atom formedby the loss or gain of one of more electrons.Sodium Chloride:Appears naturally in high concentrations: Uyuni Salt Flats – Bolivia Lesson 2 – Mineral IIMinerals Required in the diet (wide set)Ca (Calcium):The most prevalent/common mineral in our diet, which we need for our teeth & bones.P (Phosphorus):Also important for our teeth & bones
V (Vanadium)Mo (Manganese) Also important to our diet Sn (Tin)Mineral = Micronutrients ~1-1 gram/day 1 gram – all the calcium we would need daily Alittle more than 1 gram – the other minerals daily Mineral Intake:Salt:6 grams/day~ 40% of this is sodium2.4g or about twice the recommended intake **People consuming too much salt (volume)Sodium Chloride (Na & Cl):Table salt Different types of saltMorton SaltKosher SaltFleur de Sel All sodium chloridewith different minerals added which Hawaiian Sea Salt aren’t always defined on the boxPink Himalaya Salt Too much Salt?HypertensionHigh Blood Pressure
Normal & High Blood Pressure:Activity 2: SodiumQuestion 1Which of the following foods contains the highest amount of sodium per serving?Answer: Cottage CheeseA great deal of sodium may be added to foods during the production process. Below are the amounts of sodium found in a serving of each food you categorized.High SodiumLow Sodium2% Cottage Cheese (1 cup) = 746mgCorn tortilla (26 g)= 3mgGreen Olives ( 10 large) = 607 mgVanilla ice cream (1/2cup) = 53mgRaw egg (1 large) = 71mgReference: United States Department of Agriculture (USDA) National Nutrient Database for Reference StandardsPotassium (K+): Salt, but not the normal salt we used (Potassium Chloride) K+ Cl- Used to flavor food for those with high blood pressure Foods with A lot of Potassium: Bananas (#10)Potatoes (50% more than bananas per gram)Potassium (K+) = Bigger spherical size than NaSodium (Na+) = Smaller sizeSize is associated with how much water can accumulate around those moleculesBalance of electrolytes concentrations is important in the body in the way they transport other materials ** If your body is working properly, you shouldn’t have a problem with this.
Activity 3: PotassiumQuestion 1Bananas are commonly thought of as a rich source of potassium (K+) but as you saw in the videothere are other foods that contain surprisingly high amounts of this mineral.Which of the following foods contains the highest amount of potassium per serving?Answer: Dried Apricots Amount of Potassium per 100g serving:FoodsDried Apricot (no sugar added) 1162 mg
