| Question | Answer |
|---|---|
| Specific heat | the heart in calories required to raise the temperature of gram of a substance one degree centigrade |
| Solubility | the amount of solute dissolved in 100gHtz at a specific temperature |
| Saturated | being the most concentrated solution that can persist in the presence of an excess of the dissolved substance |
| Specific heat | the heart in calories required to raise the temperature of gram of a substance one degree centigrade |
| Solubility | the amount of solute dissolved in 100gHtz at a specific temperature |
| Supersaturated | containing an amount of a substance greater than that required for saturation as a result of having been coded from a higher temperature to a temperature below that at which saturation occurs |
| Saturated | being the most concentrated solution that can persist in the presence of an excess of the dissolved substance |
| Unsaturated | capable of absorbing or dissolving more of something |
| Base | a chemical substance that reacts with an acid to form a salt and turns red litmus paper blue |
| Supersaturated | containing an amount of a substance greater than that required for saturation as a result of having been coded from a higher temperature to a temperature below that at which saturation occurs |
| Neutralization | the quality or state not electrically charged and neither a base or acid |
| Acid | a chemical compound that tastes sour and forms a water solution which turns blue litmus paper red |
| Titration | a method or the process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution |
| Base | a chemical substance that reacts with an acid to form a salt and turns red litmus paper blue |
| pH | the negative logarithm of the effective hydrogen-ion concentration of hydrogen-ion activity in gram |
| Neutralization | the quality or state not electrically charged and neither a base or acid |
| Titration | a method or the process of determining the concentration of a dissolved substance in terms of the smallest amount of a reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution |
| pH | the negative logarithm of the effective hydrogen-ion concentration of hydrogen-ion activity in gram equivalents per liter used in expressing both acidity and alkalinity on a scale whose values run from 0 to 14 with 7 representing neutrality, numbers less |
| than 7 increasing acidity, and numbers greater than 7 increasing alkalinity | |
| Boyle's law | the principle that at a constant temperature tha volume of a confined ideal gas varies inversely with its pressure |
| Charles' law | the principle that all gases expand equally for the same rise of temperature if they are held at constat pressure or volume |
| Combined Gas law | shows the relationships between pressure, volume and temperature by using the combination of Charles' law, Boyle's law and Gay-Lussac's law |
| Directly proportional | the value of the result will increase with the increase of the parameter |
| Indirectly proportional | the value of the result will decrease if the parameter increases |
