More dilution normally means less conductivity. But it depends on the substance dissolved. Sugar or alcohol dissolved in water don't form free ions in water like eg. Salt does when it breaks into Na+ Cl-

The property of seawater used in induction salinometers to measure salinty is?
Induction salinometers measure the electrical conductivity of seawater. At a fixed temperature, the conductivity is approximately linearly proportional to salt concentration. The nature of the salt makes a difference, and sea salt composition varies somewhat around the world. For chemical solutions other than seawater, conductivity generally increases with increasing concentration, but the factor relating conductivity to concentration depends upon the composition of the solution. For a given concentration of salt near room temperature, conductivity increases about 2% for each degree Celsius of temperature increase because the viscosity of water decreases as the temperature rises. For solutions of strong acids, the temperature coefficient is nearer 1%/ degree. (The mechanism of conductivity in strong acid solutions differs from that in salt solutions.) Temperature coefficients are smaller at elevated temperatures. Weird nonlinearities occur in aqueous solutions below 4 degrees C, as the water begins to freeze. The temperature coefficient of seawater also depends slightly on the composition of the seawater. Commercial induction salinometers which calculate temperature corrections assume some standard composition of seawater, such as that found in Copenhagen bay. This may yield errors for seawater which has been concentrated by solar evaporation, such as in the Red Sea, or seawater which has been diluted by river water or ice melt.
What effects does the concentration of reactants have on the rate of the reaction?
increasing the concentration increases the rate of the reaction
How can two solutions have the same concentration if one solution has twice as much of solvent?
If one solution has twice as much solvent, but has the same concentration then it also has twice as much insolvent.
What is the solution that contains more water than what is located in the cells?
A hypertonic Solution. a solution that has a greater concentration of water than the cell content is hypotonic, meaning there is less concentration of water inside the cell, which results in an increase or an expansion of the cell.
A substance that has a pH of more than 7.0?
A Substance that has a Ph of more than 7.0 is anything basic or with a OH- Concentration exceed the H+ concentration by the Brønsted-Lowry base definition. A few examples of basic substances are soap, bleach, and most cleaning solutions, and milk also
Which of these has the greates effect on the electrical conductivity of solutions?
Influence on the electrical conductivity of solutions:- types of substances dissolved- concentration of solutes- temperature

Why do some solutions have fair conductivity?
Conductivity in solutions is all about charge carriers (ions). Ions (like sodium and chlorine ions - Na+ and Cl-) in solutions make it conduct pretty well. Sugar dissolved in water doesn't really make a solution that wants to conduct. Solutions with "fair" conductivity have ion (charge carrier) concentrations that are "modest" to "fair" and that is what make them "fair" conductors.
Two clear solutions are placed in separate beakers the first solution as a pH of 4 and the pH of the second is unknown if the two solutions are mixed and the resulting pH is 5 the second solution must?
a higher concentration of OH- ions
How does the concentration of electrolytes affect the conductivity of a solute?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
How does concentration differ in a solution?
Concentration is very variable in solutions.
On which property of solutions does the concept of concentration rely?
The amount of solute relative to solvent is what determines concentration. Therefore, solute is the property of solutions on which the concept of concentration relies.
What happens to the concentration as the solution is diluted?
When a given solution is diluted, it concentration is usually lowered as well. The density of the given solution also changes when the solution is diluted.
Why do covalent solutions have poor electrical conductivity?
Covalent compounds do not dissociate into ions.
What kind of solutions have good conductivity?
Solution of electrolytes are good electricity conductors.
If conductivity solution is frozen will it change the conductivity?
Conductivity of frozen solution will decrease tremendously, as iones will be immobile in frozen solution. However, upon defrost, the conductivity should return to standard value, if salt has not percititated out of solution irreversibly, which is not ususally the case with conductivity standard solutions.
