What effect does the temperature have on solution rate?
acidic buffers increase pH as temperature increases, basic buffers decrease pH as temperature increases I am still searching for the reason.
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
Exothermic
Which solution containing 2.4g salt per 5ml of water are saturated at room temperature?
This salt solution is saturated at room temperature.
What happens to gas solute in a solution when the temperature decreses?
The solubility of gas increases as the temperature decreases.
Difference between isothermal and isoperibol calorimeter?
An isothermal calorimeter is a tool used to bind small molecules to larger macromolecules, and determine the thermodynamic parameters of interactions in a solution. An isoperibol calorimeter measures the heat created by a sample burned under an oxygen atmosphere in a closed vessel surrounded by water, in controlled conditions. The measurement is known as a BTU value.
In Part B of the experiment a student mixes 25.0 mL of 1.1 M HCl (aq) with 25.0 mL of 1.000 M NaOH (aq) in a well-insultated calorimeter and observes that the temperature of the solution increases by?
In Part B of the experiment, a student mixes 25.0 mL of 1.1 M HCl (aq) with 25.0 mL of 1.000 M NaOH (aq) in a well-insultated calorimeter and observes that the temperature of the solution increases by 6.90 °C. (These are similar conditions as the previous two problems.) How many moles of water are formed?
What is the solution containing the maximum of solute possible at that temperature?
A saturated solution

This salt solution is saturated at room temperature.
What effect does the water temperature have on the solution rate?
if the temperature of the water is hot, then the sugars will dissolve faster because hot temperature increases solution rate.
What happens to gas solute in a solution when the temperature decreses?
The solubility of gas increases as the temperature decreases.
What happens when the temperature of a saturated copper sulphate solution is increased?
The solution will become unsaturated as the saturated concentration will increase. Solubility increases with temperature.
As the temperature of an aqueous solution increases what does the concentration of gas dissolved in the solution do?
An aqueous solution has 0.0070 gram of oxygen dissolved in 1000. grams of water. calculate the dissolved oxygen concentration of this solution in parts per million?A. 17ppm B. 27ppm C. 7ppm D. 7ppm

What solution contains more solute than predicted at a given temperature?
A solution containing more solute than can theoretically be dissolved at a given temperature is called a supersaturated solution.
A solution containing all the solute that a solvent can dissolve at a certain temperature and a pressure is called an?
saturated
