Web27 May 2024 · We assume Sr(OH)2 is a strong base, such that Sr(OH)2(s) H2O(l) −−−−−→ Sr2+(aq) + 2OH−(aq) and thus, it supposedly gives rise to 0.026 × 2 = 0.052 M OH−. As a result, pOH = − log[OH−] = −log(0.052) = 1.28 But clearly, we have the pOH and not the pH. At any temperature, pH+pOH = pKw, and at 25∘C, pKw = 14. Therefore: pH = 14 −1.28 = … WebBecause Sr(OH) 2 is slightly soluble in cold water, its preparation can be easily carried out by the addition of a strong base such as NaOH or KOH, drop by drop to a solution of any soluble strontium salt, most commonly Sr(NO 3) 2 (strontium nitrate).

WebThe value of this constant at 25 o C is 1.0 x 10-14. As you can see from the very small value of K W, water is not very dissociated at room temperature and our assumption that the concentration of water being constant is a good one. For pure water, the values of [H 3 O +] and [OH-] are equal and thus their values are both 1.0 x 10-7. If there ...
