In an ionic solution, a current consists of Ca2+ ions (of charge +2e) and Cl− ions (of charge −e) traveling in opposite directions. If 5.15×1018 Cl− ions go from A to B every 0.530 min , while 3.24×1018 Ca2+ ions move from B to A, what is the current (in mA) through this solution? Part A) If 5.15×1018 Cl− ions go from A to B every 0.530 min , while 3.24×1018 Ca2+ ions move from B to A, what is the current (in mA) through this solution? Part B) In which direction (from A to B or from B to A) is the current in part A going?

3. We usually think of a metal when we are imagining a conductor; but an ionic solution is a conductor too. As an example, consider an ionic solution of calcium ions (Ca2+) with charge 2e and chlorine ions (Cl-) with charge -e. a. If 5.11 x 1018 chlorine ions go from a to b every 30.0 seconds, and 3.24 x 1018 calcium ions are going from b to a during the same interval, what current in mA is flowing through...

In an ionic solution, 5.0×1015 positive ions with charge +2e pass to the right each second while 6.0×1015 negative ions with charge −e pass to the left. What is the magnitude of current in the solution? (mA) What is the direction of current in the solution? (left or right?)

sum The direction of current is the direction that charge would flow if present. positive ions right opposite both positive and negative Negative charges moving to the left, result in a current moving to the In most metals, it is the that move and therefore the current moves in the direction as the moving charges ions In an ionic solution, you can have moving positive left difference The total or net current is the of all of the currents taking...

The mobilities of H+ and Cl at 22°C in water are 3.623 x 10-3 and 7.91 x 10-4 cm2 s-1 v1, respectively. What proportion of the current is carried by the protons in 1.0 x 10-3 mol L-1 hydrochloric acid? What fraction do they carry when the NaCI is added to the acid so that it is 1.0 mol L-1 in the salt? Note how concentration, as well as mobility governs the transport of current. (a) Given that the electric...

Conductivity of Solutions For Che 2A at RCC Introduction Electrolytes are compounds which conduct electricity when dissolved in water. Strong electrolytes consist of ionic compounds which dissociate completely when dissolved in water, AND molecular compounds which completely ionize when dissolved in water. The reactions below illustrate the dissociation reaction of strong electrolytes: Na (aq) + Cl(aq) но NaCl(s) H30 CaBra(s) HO HCl(e) Ca(aq) + 2Br (aa) H*(aq) + C'(aq) Conductivity is a measure of the ability of water to pass...
