Oxidation state of chromium in dichromate ions?
+6 oxidation state
Steps to make tea using words solution solvent solute dissolve soluble insoluble filtrate residue?
step 1: take a container and add 50 ml of solvent (WATER) in it . step 2: boil the solvent (WATER) for 2 mintues then add insoluble (tea leaves). step 3: add soluble (SUGAR) and leave it for few mintues. step 4: stir the solution (TEA) until the sugar is dissolved and add liitle solute (milk) according to taste . step 5: take a filtrate keep it on a cup and pour the tea . step 6: the insoluble residue will be left throw it out and you tasty recipe will be ready.
What is the formula for potassium floride?
The chemical formula of potassium ferrocyanide is K4[Fe(CN)6].3H2O; the crystals are monoclinic.
How many moles potassium chlorate must be used to produce 6 moles of oxygen gas?
We need 3 moles of potassium perchlorate.
How many moles of potassium chlorate must be used to produce 6 moles if oxygen gas?
Four moles of potassium chlorate are needed.
Is Potassium nitrate a solid?
Corrected answer:NO,MOST of the potassium salts and ALL of the nitrates are SOLUBLE, not insoluble!!!So potassium nitrate is NOT INsolubleSome potassium salts and complexes are insoluble like Potassium Hexanitritocobaltate(III) = K3[Co(NO2)6] , etc.
What is the oxidation number of chromium in potassium dichromate?
potassium dichromate is K2Cr2O7. The oxidation number of Cr is -6. (Oxygen is -2, K is +1 so Cr must be -6)
What is the oxidation number of Cr is acidified potassium dichromate?
+6
Is KNO3 soluble or insoluble?
no (yes! - lordwelsh) 13.3 g/100 mL (0 °C) 36 g/100 mL (25 °C) 247 g/100 mL (100 °C) --------------------------------------------------------------------------- Here are some solubility rules in case you need to know other compounds' solubility: 1. All alkali metal (lithium,sodium,potassium,rubidium, and cesium) and ammonium compounds are soluble. 2. All acetate, perchlorate, chlorate, and nitrate compounds are soluble. 3. Silver, lead, and mercury(I) compounds are insoluble. 4. Chlorides, bromides, and iodides are soluble. 5. Carbonates, hydroxides, oxides, phosphates, silicates, and sulfides are insoluble. 6. Sulfates are soluble except for calcium and barium. The first rule states it is soluble because it has potassium. But in other cases two rules will say different things. Like on will say soluble and one will say insoluble so always follow the first one listed. A more specific example is AgCl. Rule 3 overtakes rule 4 so it is insoluble.
What is the equivalent weight of K2Cr2O7 fully explanation?
Equivalent weight of potassium dichromate = Molecular mass/6 = 294,185/6 = 49,0308
What is the oxidation number of one chromium atom in potassium dichromate?
Potassium dichroamte is K2Cr2O7, in the dichroamte ion both Cr atoms have an oxidation number of +6.
Why potassium dichromate solution changes to green colour when it is added to ferrous ammonium sulphate solution?
This is why: Ferrous ion, Fe++ is a reducer, by tending to being oxidized towards Fe+++ Cr in dichromate is +6 and by being reduced it becomes Cr+++ which is green
Why you can use 4.9035 g K2Cr2O7 to prepare 0.1 n solution?
The equivalent of potassium dichromate is the molar mass/6: 294,1846/6=49,307666. For a 0,1 N solution: 49,30766/10 = 4,93076 g
Equation between potassium dichromate and iron sulfate?
6 FeSO4 + K2Cr2O7 + 7 H2SO4 = 3 Fe2(SO4)3 + K2SO4 + Cr2(SO4)3 + 7 H2O
What chemical compound is Ag2CO3?
No Ag2CO3 is not soluble Here are some solubility rules: 1. All alkali metal (lithium,sodium,potassium,rubidium, and cesium) and ammonium compounds are soluble. 2. All acetate, perchlorate, chlorate, and nitrate compounds are soluble. 3. Most of silver, lead, and mercury(I) compounds are insoluble. 4. Chlorides, bromides, and iodides are soluble except those at 3. 5. Carbonates, hydroxides, oxides, phosphates, silicates, and sulfides are insoluble except those at 1. 6. Sulfates are soluble except for calcium and barium and those at 3. Rule 3 says silver is insoluble. For a different compound it might have a disagreement with rules one saying its soluble one saying insoluble. Always go with the first one listed in these rules. A more specific example is AgCl. Rule 3 overtakes rule 4 so it is insoluble. ~Higgins~
What are the keywords for solution in science?
1. Mixture 2. Solute 3. Solvent 4. Dissolve 5. Filtering 6. Insoluble 7. Soluble 8. Solution etc...
What is the best type of fertilizer for centipede lawns?
Nitrogen (N), phosphorus (P), and potassium (K) are the main nutrients that plants need to survive. Complete fertilizer contains those three ingredients and they are listed clearly as the N-P-K ratio. So, if a package of fertilizer states that its N-P-K ration is 10-6-6, then the fertilizer contains 10% nitrogen, 6% phosphorus, and 6% potassium. Water-soluble nitrogen satisfies the plants needs quickly, while insoluble nitrogen must be broken down by organisms in the soil before the plants can be fully satisfied.
