Solubility of Manganese(II) Nitrate

The video tutorial explores the solubility of manganese(II) nitrate (Mn(NO3)2) in water. It begins by introducing the concept of solubility and the specific compound in question. The instructor then refers to general solubility rules, highlighting that nitrate ions (NO3-) are typically soluble. To confirm this, data from Wikipedia is presented, showing that manganese nitrate is highly soluble in water at 10°C, with a solubility of 118 grams per 100 milliliters. The video concludes by affirming that manganese(II) nitrate is indeed soluble in water.

What is the general solubility rule for nitrate ions?

• Nitrate ions are generally insoluble.

• Nitrate ions are soluble only in cold water.
