ABSTRACTThis study investigated to determine the effect of problem based on practical to the students’learning outcomes and science process skill on Solubility and Solubility Product Constant materials at grade XI of Science class, MAN 2 FILIAL Pontianak. Using pre experimental and one-group pretest post-test designs, this study employed grade XI students of Science class. The data collection technique used were measurement and observation. While the instruments utilized were pre-test, post-test, and science process skill test. The results of learning outcomes analysis of pretest, post-test, and science process skill test by using Wilcoxon (SPSS 17,0 for windos) and run with an alpha level of .05 (5%) revealed that this test rejected Ho and accepted Ha (P value (0,00) < (0,05). The Effect Size (ES) of learning outcomes was 3,53 and considered high. The Z table contributed significant influence of 49,98%. Furthermore, the Solubility Product Constant indicated 2,90 and considered high, as well. The Z table contributed significant influence of 49,81%. As a result there was correlation of problem based on practical to the students’ learning outcomes and science process skill on Solubility and Solubility Product Constant materials.Keywords: learning outcomes, problem based on practical to the students’ learning outcomes, science process skill

Solubility and Complex-Ion Equilibria broadens the previous chapter’s coverage of equilibria to include aqueous systems containing two or more solutes of slightly soluble ionic compounds and the formation of metal complexes in solution. Solubility equilibria which allow quantitative predictions of how much of a compound will dissolve under given conditions are covered. The meaning of the solubility product constant (K sp) and how to calculate it from molar solubility values is presented. Also discussed is determination of molar solubility from K sp. Calculations demonstrate how to predict the formation of a precipitate by comparing the ion product or solubility quotient (Q) with K sp. Formation constants of complex ions and calculations involving complex ion equilibria are explained.

Abstract Extraction of uranium from seawater is critical for the sustainable development of nuclear energy. However, the currently available uranium adsorbents are hampered by co-existing metal ion interference. DNAzymes exhibit high selectivity to specific metal ions, yet there is no DNA-based adsorbent for extraction of soluble minerals from seawater. Herein, the uranyl-binding DNA strand from the DNAzyme is polymerized into DNA-based uranium extraction hydrogel (DNA-UEH) that exhibits a high uranium adsorption capacity of 6.06 mg g−1 with 18.95 times high selectivity for uranium against vanadium in natural seawater. The uranium is found to be bound by oxygen atoms from the phosphate groups and the carbonyl groups, which formed the specific nano-pocket that empowers DNA-UEH with high selectivity and high binding affinity. This study both provides an adsorbent for uranium extraction from seawater and broadens the application of DNA for being used in recovery of high-value soluble minerals from seawater.
