Postby Jasmine 2C » Sat Dec 07, 2019 3:41 am

How do you know the acid and base needed to create zinc nitrite in part C of the question: "Select an acid and a base for a neutralization reaction that results in the formation of (a) potassium bromide; (b) zinc nitrite; (c) calcium cyanide, Ca(CN)2; (d) potassium phosphate. Write the balanced equation for each reaction."?

Make sure you know that zinc nitrate is Zn(NO2)2 because Zn has a 2+ charge. Then you attach and 2 OH- to Zn2+ in the reactants and attach and H+ to NO2-. A neutralization always forms water and the salt, so balance the chemical equation.
