this seems to happen mostly when the temperature gets high.

this only happens maybe 20-30% of the time. it seems worse when the ambient temperature gets warm.

total of 15L. 300g stannous chloride with 2L DI water. 1200g sodium hydroxide with 12L DI water. mix both solutions seperate then combine after sodium hydroxide solution has cooled to ambient temp. top with DI water to 15L.

it's a slow reaction and at a high temperature the solubility of the tin (II) hydroxide goes up so more stays in solution before the solid can precipitate.
and by the way, a word of warning to all, hydroxides are not insoluble, just far less soluble than other compounds.

Stannous chloride at little high temperature undergoes self oxidation/reduction reaction in the presence of a strong base like sodium hydroxide and some of the stannous oxidized to stannic while equivalent amount gets reduced to tin metal. Please note both the products stannic hydroxide and tin metal are insoluble in water.

NaOH (sodium hydroxide) is a very reactive base; likewise, it will react readily with SnCl4 (Tin IV Chloride), to form an insoluble precipitate Sn(OH)4. Hydroxides are insoluble.

Simply due to the precipitation of Sn(OH)2

Sn(OH)2 isn't soluble in water
