Write the formula for the compound magnesium bromite. Determine the ions, and write the correct formula for the ionic compound formed by each of the following. a. sodium and phosphorus b. magnesium and oxygen What is the formula for an ionic compound composed of the ions X2+ a...
In a molecular compound, such as, for example, water, H2O, or ethanol, C2H5OH, each unit of the substance, the molecule, consists of the number of atoms shown in the formula. In an ionic compound, such as common salt, NaCl, or magnesia MgO, the formula tells us the correct ratio ...
Ionic strength is a unitless quantity that accounts for the charge and concentration of all ions in a solution. It is used to estimate the difference between the activity (e.g., as measured by an ion-selective electrode) and the calculated concentration of the ion. The formula for calculating...

The crown ether used in this study is 1,10-diaza-18-crown-6-ether (DA18C6, molecular formula: C12H26N2O4. Fig 1a), which can bind Na+ strongly37. The narrowest part of the cavity is ~0.26 nm, which is larger than the diameter of Na+ (0.20 nm) and slightly smaller tha...
Write a net ionic equation for the reaction that occurs, when aqueous solutions of sodium hydroxide and hydrochloric acid are combined. What is the cation reaction with water, cation K_a, anion reaction with water, anion K_b, acidic base prediction, and pH ...
We prepared the CS-TPP NPs by the ionic gelation method, using diluted acetic acid and TPP as the polyanion. First, 5 mL of low molecular weight CS solution was dissolved in 1% v/v acetic acid, with pH adjustment using 20% sodium hydroxide solution; subsequently passed through a 0.22 μ...
