question 1:
ion charges: (na^+, cu^2+, oh^-,
write a balanced chemical equation for the change you observed in the laboratory

note that the reaction in this experiment is:
copper (ii) nitrate + sodium hydroxide → copper (ii) hydroxide +sodium nitrate

question 2:
ion charges: (na^+, fe^2+, oh^-, so4^2-)
write a balanced chemical equation for the change you observed in the laboratory

note that the reaction in this experiment is:
iron (ii) sulfate + sodium hydroxide → iron (ii) hydroxide + sodium sulfate

question 3:
ion charges: (na^+, fe^3+, oh^-, no3^-)
write a balanced chemical equation for the change you observed in the laboratory

note that the reaction in this experiment is;
iron (iii) nitrate + sodium hydroxide → iron (iii) hydroxide + sodium nitrate
how many grams of sodium nitrate formed when 1.5 moles of iron (iii) nitrate reacted with excess of sodium hydroxide? note: use a periodic table, write units for your result and show your work ☺
