What else can I help you with?
What has to be added to a solid before it affects pH paper?
In order to take a pH reading, water must be added to the solid. The water should be purified and have a known neutral pH.
What must occur for a solution to form?
The correct answer is as follows: One Substance Must Dissolve In Another.
Is there a maximum temperature for a solid to dissolve?
The temperature must be under the decomposition temperature of the substance.
What must be added to a solid to cause it to melt?
Heat must be added to a solid to cause it to melt. As the temperature increases, the solid gains enough energy to overcome the forces holding its particles together, causing them to move more freely and transition into a liquid state.
How dissolve an ionic solid in water you must first disrupt the ionic bonds holding the ionic lattice together?
in order for an ionic solid to dissolve, the ionic bonds must break through the reaction with water. So yes, what you said is correct. For example a solid NaCl is mixed with water: H20 + NaCl (s) --> Na+ + Cl- + H30+ + OH-
What is the mixture in which more of the same solute can be dissolved?
A mixture in which more of the same solute can be dissolved is called a saturated solution. In a saturated solution, the solvent has reached its maximum capacity to dissolve the solute at a given temperature and pressure. If more solute is added beyond this point, it will not dissolve and will remain as a solid in the mixture. To dissolve more solute, the temperature or pressure of the solution must typically be increased.
Why must HCl be added to the solid after the reaction with zinc is completed?
To reduce the zn5+ to zn2+
What must e added to the system to move from a solid to a liquid and then to a gas?
heat energy
Which solid makes a saturated solution when you add 40g of it to 100g of water?
Assuming the solid is the limiting reagent, the saturation point of the solution is reached when no more solid can dissolve in the solvent, creating a saturated solution. The solubility of the solid must be known to determine if 40g can fully dissolve in 100g of water.
Must quantities have different units before they can be added or subtracted?
no
How could you dissolve more solid solute in saturated solution in liquid solvent?
Increasing the temperature the solubility increase.
Do solutions dissolve solids?
yes but it depends on the temperature of the solid e.g. steel must be very hot to absorb any solution as a cooling agent. like block and wood they do but very slowly.
