name a substance...which when oxidised gives sulphur
if sodium hydrogen carbonate is an acidic salt how can it turn to blue when neutral litmus sol. is added?
what is the metallic oxide which cannot be reduced by normal reducing agents?
What is observed when, neutral litmus solution is added to sodium hydrogencarbonate solution.
What is the reaction for oxidation of ferrous sulphate to ferric suphate by a strong oxidising agent?
which is more strong conc.sulphuric acid or conc.HCL ?
how can Na + O2 can form Na2O didn't understand ?
Why sulphuric acid is considered strong acid and carbonic acid is considered as weak acid while both are dibasic acid.
Please explain???
name any two bases which are not alkalis
NAME A NON METALLIC ELEMENTWHICH FORMS ACIDIC & NEUTRAL OXIDE ?
how can we determine that which product is formed by which type of reaction as;which of the method A B C D OR E IS GENERALLY USED FOR PREPARING THR CLORIDES LISTED BELOW FROM 1 TO 5 :A - ACTION OF AN ACID ON A METAL ( B ) ACTION OF AN ACID ON AN OXIDE OR CARBONATE( C ) DIRECT COMBINATION ( D ) NEUTRALISING OF AN ALKALI BY AN ACID ( E ) PERCIPITATION( 1 )COPPER CLORIODE (2) IRON 2 CLORIDE ( 3 ) IRON 3 CLORIDE (4 ) LEAD 2 CLORIDE (5) NACLEACH METOD IS TO BE USED ONCE
how can we determine that which product is formed by which type of reaction as;
what is titration of Na and K salts ?
When Copper Sulphate is added in little quantity of Ammonium Hydroxide then a pale blue ppt is observed, but when Copper Sulphate is added in excess of Ammonium Hydroxide then a deep blue solution is observed. Please explain why?
How is dilute hydrochloric acid a stronger acid than concentrated hydrochloric acid?
how should i learn all these reactions......is there any tact...????
