well the answer is calcium sulfate as it is a neutral substance and does not change PH( a slight change may be noticed which is negligible) and so it is not a liming substance.when added to the soil the calcium in the gypsum(calcium sulfate) will displace Hydrogen on a clay particle. the hydrogen however would remain in the soil solution and the ph wont change because of the absence of carbonate and hydroxideWhen added to the soil, the calcium in the gypsum can displace the hydrogen on a clay particle. The hydrogen, however, woun in the soil solution and the pH would not change because of the absence of carbonate.20 Which calcium compound does not increase the pH of acidic soils?
A calcium carbonate
B calcium hydroxide
C calcium oxide
D calcium sulfate
answer AND reason please????

Um, guys, quick question. Cu doesnt react with water right? How does it form Cu(OH)2 then?
a mutual induction is obtained by a 2 volt dc cell by switching the switch on and off continuously a compass needle is deflected momentarily what will happen if i change the 2 volt dc cell with 2 volt ac supply
my teacher says that fig1.a produces more current can u explain why???
thank you soooooo much!Cu reacts with water, but this reaction is VERY slow due to its relatively unreactive nature.
Copper left in moist air will form CuCO3 and Cu(OH)2 in a roughly 1:1 proportion..
2 Cu (s) + H2O (g) + CO2 (g) + O2 (g) → Cu(OH)2 (s) + CuCO3 (s)
thank you!Its not a neccesity that u react the Cu with water directly u have indirect routes,Cu(OH)2 is insoluble u cud make it by Precipitation method !
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
