Calculate the mass of zinc hydroxide that is formed by the interaction of 47 g of zinc sulfate with potassium hydroxide.
| January 12, 2021 | education
Zinc sulfate reacts with potassium hydroxide according to the reaction:
ZnSO4 + 2KOH = Zn (OH) 2 + K2SO4.
Based on the molar masses of the compounds, it can be argued that 99 g of hydroxide is formed from 161.5 g of zinc sulfate. Let’s make the proportion:
47 g – x g
161.5 g – 99 g
From here we find that x = 28.8 g. That is, from 47 g of sulfate, 28.8 g of zinc hydroxide is formed.
