Are the charge balances
1. Aqueous solutions should be electrically neutral. In other words, cations and anions should be balanced...
1. A rain sample has the following composition of major cations and anions, in µmol/L. Cations: H+: 60; Ca2+: 10; Mg2+: 15; Na+: 60; K+: 5; NH4+: 40. Anions: Cl-: 60; NO3-: 42. What is the sum of positive charges of that sample, in µmol/L? 2. Of that same sample, estimate the concentration of SO42-, in µg/L, in that sample if you assume a charge balance in the sample and no other major anions or cations present other than the...
Completing and Balancing Neutralization Reactions 10 of 18 For example, if you have a cation with a 1+ charge and an anion with a 2-charge, you will need two cations to balance the charge: I(1+ charge on cation)(2)]+[(2-charge on anion)(1)) = (+2) + (-2) = 0 Complete the following statements regarding the number of cations and anions present in the various ionic compounds. Match the numbers to the appropriate blanks in the sentences below. Make certain each sentence is complete...
