WebSubstances that dissolve in water to yield ions are called electrolytes. Electrolytes may be covalent compounds that chemically react with water to produce ions (for example, acids and bases), or they may be ionic compounds that dissociate to yield their constituent cations and anions, when dissolved. WebThe bonds in salt compounds are called ionic because they both have an electrical charge—the chloride ion is negatively charged and the sodium ion is positively charged. … Web8 nov. 2024 · First, determine how many moles are present in 3 grams of KCl. Start by looking up the number of grams per mole of potassium and chlorine on a periodic table. Then add them together to get the grams per mole for KCl. K = 39.1 g/mol; Cl = 35.5 g/mol; KCl = 39.1 + 35.5 = 74.6 g/mol; For 3 grams of KCl, the number of moles is: bjm bathrooms plymouth
