'''Crosslinking PVOH Films With 0.7M HCl and neutralizing . | '''Crosslinking PVOH (MW:146,000-186,000) Films With 0.7M HCl and neutralizing .6 Molar sodium bicarbonate'' | ||
*To high of a molecular weight will remake with with a lower molecular weight | |||
*MW: 22,000 will be used instead for this....higher molecular weight is to thick for this type of reaction with crosslinking with glutaraldehyde | |||
* 20ml of 100% H2So4 in 1 L of H20 was use for the fixant will determine amount of H+ ions in solution to determine concentartion of HCL | |||
**20ml* 1.84g/ml ÷ 98.079g/mol = 0.375moles of H2SO4 ÷ 1 Liter= 0.369 Molar H2SO4 | |||
** assume complete dissociation | |||
** 0.369mols of H2SO4/L * 2mols HCl/1mol of H2SO4 = 0.7M HCl, which is equal to 6ml of 12 M HCl in 94 ml of H2O | |||
* To neutralize a NaHCO3 solution will be made, 0.7 M NaHCO3 | |||
