Ph of strontium hydroxide
WebCa (OH) 2 ( K sp = 5.02×10−6) [6] is far more soluble than Mg (OH) 2 ( K sp = 5.61×10−12) and drastically increases the pH value of seawater from 8.2 to 12.5. The less soluble Mg (OH) 2 precipitates because of the common ion effect due to the OH− added by the dissolution of Ca (OH) 2: [7] Mg2+ + Ca (OH)2 → Mg (OH)2 + Ca2+ Uses [ edit] WebNational Center for Biotechnology Information. 8600 Rockville Pike, Bethesda, MD, 20894 USA.
