Q / A molecule tends to increase water solubility because of an increase in the molecular weight of the compound without a change in polarity reduces solubility in water. ?
يميل الجزيء إلى زيادة قابلية الذوبان في الماء بسبب زيادة الوزن الجزيئي للمركب دون تغيير في القطبية يقلل من الذوبان في الماء.
No, it tends to decrease the solubility of water becase of the increase of mwt of compound without change in polarity
لا، إنه يميل إلى تقليل قابلية ذوبان الماء بسبب زيادة Mwt. من المركب دون تغيير في القطبية

Q.3// briefly explain the effect of
adding KI in preparaing Lugol's solution? *
lodine is considered slightly soluble(additional polar
groups) in water, so we add (KI) to increase water solubility
that because formation of tri-iodine ion a s salt-soluble in
water.
