Solutions Vocabulary
| Question | Answer |
|---|---|
| solution | Is a homogeneous mixture of one or more substances called solutes |
| solute | Is a homogeneous mixture of one or more substances called solutes |
| solvent | Dissolved in another substance |
| homogeneous | “Of uniform composition that is the same substance through out” |
| compound | Is a chemical union that cannot be separated |
| mixture | Is a physical union that can be separated by physical means |
| heterogeneous | Diverse in content |
| solubility | Removing the water from salt |
| concentration | Is measured by the number of grams of solute dissolved in water |
| Like dissolves like. | It means that solutes and solvents that have similar molecular polarity |
| dipole | Haves neutral charge |
| polar | Is easily dissolvable |
| nonpolar | Harder to dissolve |
| organic | Are carbon based compounds are nonpolar and will not dissolve in water |
| surface area | Of a solid solute also affects the rate of its solubility |
| agitation | Means to shake up |
| How does temperature affect solubility? | It changes the temperature which cause a reaction |
| Rate of dissolution | It how fast it will dissolve |
| How does pressure affect solubility? | It doesn't |
| How does surface area affect solubility? | May cause it to dissolve faster |
| How does agitation affect solubility? | Will cause it to dissolve faster |
| supersaturated | Means that no more of the solute will dissolve in the given thing |
| acid | Substance that dissolve most anything |
| Hydronium ions | Present in all aqueous acids |
| dissociate | splitting into smaller atoms and ions |
| Strong acids | Completely dissociate in water |
| Weak acids | Almost dissociate in water |
| Arrhenius theory | States that a base produces hydroxide ions in a water solution |
| base | The mains element |
| Hydroxide ions | Are in aqueous liquids |
| alkaline | A element |
| Bronsted-Lowry theory | And acid is a proton donor |
| salt | Sodium chloride |
| Neutralization reaction | Double displacement reaction |
| pH scale | Short for potential hydrogen |
| logarithmic | Tenfold hydrogen |
| Reciprocal scale | Means ph values decrease |
| indicator | The shows of what's happening or whats going to happen |
| Litmus test | it's where you drop litmus on paper |
| pH meter | Measures ph |
| Glass electrode | A solution and electroloads which hold a stable voltage |
| electrolytes | Special kind of conductor |
| Electrical conductivity | Create a electrical charge |
| nonelectrolytes | Are acids that are strong or not |
| Strong electrolytes | Are strong |
| Weak electrolytes | Not strong are weak |
| cathode | Negative charged electrode y which enter an electrical device |
| electrode | Connect to the power source |
| anode | Has a neg charge |
| cathode | Negatively charged electrode |
| calibration | The action or process of calibrating |
| Buffer solutions | an aqueous solution consisting of a mixture of a weak acid and its conjugate base |
