Increasing pH , as in some aged food products , decreases the solubility , and Ksp ( ' ) = [ Ca ( 2 + ) ] [ Pal ( - ) ] [ OH ( - ) ] is found constant rather than Ksp = [ Ca ( 2 + ) ] [ Pal ( - ) ] ( 2 ) in agreement with an initial precipitation of Ca ( OH ) ( Pal ) , which slowly may convert into Ca ( Pal ) 2 . Ca ( OH ) ( Pal ) has a solubility minimum at physiological ionic strength with Ksp ( ' ) = ( 1 . 4 +/- 0 . 4 ) 10 ( - 16 ) M ( 3 ) .
 Chemical: Ca ( 2 + ) ] [ Pal ( - ) ] [ OH ( - ); Chemical: [ Ca ( 2 + ) ] [ Pal ( - ) ] ( 2 ); Chemical: Ca ( OH ) ( Pal ); Chemical: Ca ( Pal ) 2 . Ca ( OH ) ( Pal )
