Example 7 No. 1 sodium silicate solution (S t Oy: 35.0 h,
Nα, 0:1Z5ch) 772 and sodium hydroxide 242
(NaOH content: 0.6 mol) was diluted in water and the total amount was 16 mol.
This is called liquid C (Sin, min: 0.45 mol). Next, zinc sulfate (heptahydrate) 216? was dissolved under hydraulic pressure to make a total amount of 1 t, and this was designated as Solution D (Zn0 min: 0.75 mol). Furthermore, sodium aluminate solution (At, 03:
20.5%, NatO: 19.5%) 751 was diluted in water to make a total volume of 1 t, and this was added to Solution E (At, 08 minutes:
0.15 mol). 1 ton of water was placed in a 5 ton beaker, and while stirring, solutions C, D, and E were each added at the same time at a rate of 25 CC/min.
