water and its properties

• solubility - ability of solute to dissolve in a solvent
• true or false: key role of solubility is on how the nutrients and medication are absorbed
• Polarity - ability to separate charges
• carbontetrachloride - used to dissolve non polar substances
• oil and fats are non polar substances
• like dissolves like principle - polar substances dissolves in polar solvent; nonpolar substances dissolves in nonpolar solvent
• H20 is a dipole
• dipole - allows water to interact and dissolve ionic compound
• acid-base reaction - chemical reaction between acid and bases; producing salt, water, and gas
• Salt is only dissolved in H20 because of ionic bond
• sugar can only be dissolved in H20 due to polar covalent bond
• gelatin can be partially dissolved in H20 while minimal solubility in CCL4 (carbontetrachloride)
• copper sulfate (CuSO4) can only be dissolved in H20
• butter is unlikely to dissolved in H2O but can be dissolved in CCl4 (carbontetrachloride)
• ethanol is dissolved more in h2o than CCl4 (carbontetrachloride) because of the present of hydrogen
• ethanol can be mixed in CCl4 (carbontetrachloride) because it is slight polar
• H20 dissolved ionic and polar substances due to hydrogen bonding and polarity
• polar substance like water dissolve substances with similar polarity
• due to the imbalance of charged in H20, it allows to interact with a new polar substances
• CCl4 rely on weaker forces like vander waals forces; effective with other non polar substances
• powdered citric acid - used in acid-base reaction
• sodium bicarbonate - used in acid base reaction
• expected outcomes: fizzling and bubbling due to CO2 gas
• chemical reaction: acid-based neutralization, producing sodium citrate, water, and CO2
• observations: bubbling upon mixing, indicating the release of gas
• citric acid is an acid that reacts with sodium bicarbonate (base) to produce CO2 gas
• acid donates protons and bases accept proton and forms water and CO2
