6-2: Acid and Base properties

Electrolytes are ionically bonded with a positive and a negative ion. All electrolytes can dissloved in water, so when it dissolves it forms an ionic solution.The electrolytes is a substance the ions break apart when dissolved in water and the charges are free to move and allow the electric current to move through it. On the other hand non electrolytes are not soluble in water and the ions do not break apart to allow an electric current to travel through them. Electrolytes are salts in the body that can conduct electricity and are found as fluid, tissue and blood In your nervous system electrolytes conduct electricity and allow the passage of electric currents to travel through your body to signal a function for your body to preform.

An indicator changes the acid or base a color according to their ph. A ph of less than 7 is a acid and a ph of more then 7 is a base. Acids contain the ion H+ and bases have the ion OH-. An indicator is a natural die changing different colors because of the sensitivity to the ph. An indicator is a weak acid and when adding  to much to a solution you may interfere with the chemical reaction. When tasting the acid it came off as sweet and sour like sour patch kids candy and the base was more bitter and salty is like baking soda. When adding an acid and base together the opposite ions bond and form a neutral solution with a ph of 7 this is a double replacement reaction resulting in a salt and water solution. In our lab we added magnesium powder to the acid we saw a bubbling and fizzing reaction and when added to the base you saw no reaction. This is because both magnesium and the aid are positively charged so you see a reaction when added in base these opposite ions attract and form a neutral solution of salt and water. When determining which solution was which my thought process was whatever takes more ind actor to change neutral color is the solution with the highest concentration(most moles of solution).

Enrichment:
A real definition of an indicator is when the natural pigment in the acid or base it may gain or loose hydroxide (OH-) depending on the ph. This changes the wavelengths of light reflected off the compound creating the color changes for different phs.
