Is Cl A cation?
Is Cl A cation?

Is co an anion or cation?
Cations and Anions
| Formula | Name |
|---|---|
| Co2+ | Cobalt(II) |
| Cr2+, Cr3+, Cr6+ | Chromium(I, II, III) |
| Cs+ | Caesium |
| Cu+, Cu2+ , Cu3+ | Copper(I,II,III) |
What are the cations?
A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.
Is co3 2 a cation?
Carbonate Ion is a polyatomic ion with formula of CO3(2-). Carbonate is a carbon oxoanion. It is a conjugate base of a hydrogencarbonate….3.1Computed Properties.
| Property Name | Property Value | Reference |
|---|---|---|
| Formal Charge | -2 | Computed by PubChem |
Why co3 has a charge of 2?
Thus overall we see carbon atom and one of the three oxygen atoms have completely filled octet while other two oxygen atoms are lacking from just one electron. SO they can receive one electrons each and as they receive these two electrons, total electron received is 2. Hence a carbonate molecule has a -2 charge in it.
Is co3 2 a strong base?
Carbonate ion, a moderately strong base, undergoes considerable hydrolysis in aqueous solution. In strongly acidic solution, CO2 gas is evolved.
Is H2CO3 stronger than HCO3?
The book says yes for HNO2 and no for H2CO3, and it gives the reason that the conjugate base NO2- is a weaker base than the conjugate base CH3COO-, so HNO2 would be a strong acid in CH3COOH; the conjugate base HCO3- is a stronger base than the conjugate base CH3COO-, so H2CO3 would act like a weak acid in CH3COOH.
Is HClO a strong acid?
Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. any acid that is not one of the seven strong is a weak acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.)
Is HClO3 stronger than HCl?
HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker. It can be simply explained by considering the stability of conjugate bases or corresponding anions. HClO3 (chloric acid) is a stronger acid than HClO2 (chlorous acid) for the following reason.
Is HCl or HOCl stronger?
The weaker the O–H bond, the stronger the acid. Cl is more electronegative than Br so HOCl is stronger acid than HOBr. In binary acids such as HBr and HCl, the H–Br bond is longer than the H–Cl bond as Br is larger than Cl. The H–Br bond is therefore weaker than the H–Cl bond and HBr is thus a stronger acid than HCl.
What is the pH of a 0.010 M solution of HCl?
2
What is pH of 0.01 m NaOH?
2. Calculate the pH of a 0.1 M NaOH solution. Alternatively we can calculate pOH = – log [OH-]= – log [10-1] = 1 and remembering that pH + pOH = 14 we get pH = 14 – 1 = 13.
What is the pH of a .001 M solution of HCl?
0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.
What is the pH of 0.01 m h2so4?
1.699
What is the pH of 10 8 M NaOH?
Explanation: This is a tiny concentration for NaOH so I would expect the pH to be close to 7 or slightly greater. For which Kw=[H+][OH−]=10−14mol2.
What is the pH of a 0.02 M solution of HCl?
1.7
What is the pH of 0.05 M HCl?
it’s a strong acid and it fully dissolves …… This solution can be considered equivalent to a solution 0.1 M (0.15 – 0.05) in HCl thus pH = -Log (0.1) = 1.
What is the pH of 1M sulfuric acid?
0
What acid has a pH of 1?
The pH scale
| Increasing pH (Decreasing Acidity) | Substances |
|---|---|
| 0 (most acidic) | Hydrochloric acid (HCl) |
| 1 | Stomach acid |
| 2 | Lemon juice |
| 3 | Cola, beer, vinegar |
What is the pH of 10 6 M HCl?
6
What is the pH of 10 2 M NaOH?
12
Which is the strongest acid?
None of the strong acids traditionally listed in a chemistry text holds the title of World’s Strongest Acid. The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid.
What is the pH of 10 3m NaOH?
At 25C,pH of 10-3M NaOH solution is. [a]3 [b]8 [c]11 [d]14. Thus, pH of the solution will be 11. Hence the correct option is (c) 11.
What is the pH of 10 7 M NaOH?
10-7
What is the pH of 10 4m NaOH solution?
That is 10 raised to the power -4.
What is the pH of 1.0 x10 5?
| Concentration (mol/L) | ||
