Mathew Mahindaratne Aside of that, it is not about being so basic high B nor so acidic low B , but about being relatively basic or acidic. Extracts of rocks or soil with high low B have relatively high low pH. Upvote 4. This discussion on Whether CaO is base or alkali or both.

There are not any convenient solvents that can be used to dissolve CaO. The short answer is that neither benzene, toluene, or any other plain hydrocarbon will dissolve CaO. Calcination of cement raw materials in the kiln produces a material called clinker. Free lime CaO in clinkers has to be closely monitored to ensure the quality of cement. Excess free lime results in undesirable effects such as volume expansion, increased setting time or reduced strength.

Silver bromide AgBr , a soft, pale-yellow, water-insoluble salt well known along with other silver halides for its unusual sensitivity to light. Barium sulfate is a metal sulfate with formula BaO4S.

Virtually insoluble in water at room temperature, it is mostly used as a component in oil well drilling fluid it occurs naturally as the mineral barite. It has a role as a radioopaque medium. It is a barium salt and a metal sulfate. It is an insoluble hydroxide which reacts with strong acid and gets dissolved.
