CSOH, commonly known as calcium hydroxide, is a compound. It is composed of calcium (Ca), sulfur (S), oxygen (O), and hydrogen (H) elements chemically bonded together. Compounds are formed when two or more different elements combine in fixed ratios, which is the case with CSOH.

No, pH 2.77 is not the correct pH for 1 M HCl. The pH of 1 M HCl should be 0 (zero) because pH is the negative log the the H+ and for 1 M HCl the [H+] is 1 M, and the negative log of 1 is 0.
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
pH=-log[H+] pH-log(1.2x10^-3) pH=2.92 since the the pH plus the pOH is always equal 14 14-2.92=11.08 so the pOH is 11.08
No, CsOH (cesium hydroxide) is a strong base because it dissociates completely in water to produce Cs+ ions and OH- ions. This makes it highly effective at accepting protons, leading to a high pH in aqueous solutions.
Yes. One of the guidelines, per my general chemistry textbook, for determining if bases are strong is as follows:M2O or MOH where M is a Group 1A metal (Li, Na, K Rb, Cs) orMO or M(OH)2 where M is a Group 2A metal (Ca, Sr, Ba)CsOH fits the pattern for the first guideline, and so is a strong base and dissociates almost completely in water.
CsOH is considered a strong base because it dissociates completely in water to form Cs+ and OH- ions. This results in a high concentration of hydroxide ions in solution, making it an effective base for neutralizing acids.
3. since the [H+]=0.001 M then pH= -log[H+] -log(0.001)=3 pH=3.
its PH is 3
CsOH is a chemical compound called Caesium Hydroxide.
Britton-Robinson buffer is a "universal" pH buffer used for the range pH 2 to pH 12. Universal buffers consist of mixtures of acids of diminishing strength (increasing pKa) so that the change in pH is approximately proportional to the amount of alkali added. It consists of a mixture of 0.04 M H3BO3, 0.04 M H3PO4 and 0.04 M CH3COOH that has been titrated to the desired pH with 0.2 M NaOH. Britten and Robinson also proposed a second formulation that gave an essentially linear pH response to added alkali from pH 2.5 to pH 9.2 (and buffers to pH 12). This mixture consists of 0.0286 M citric acid, 0.0286 M KH2PO4, 0.0286 M H3BO3, 0.0286 M veronal and 0.0286 M HCl titrated with 0.2 M NaOH.
The pH of a 0.1 M solution of HBr (hydrobromic acid) is around 1. It is a strong acid that dissociates completely in water to produce H+ ions, resulting in a low pH.
if 0.000001 is the hydrogen ion concentration the pH is 6
The pH of a solution containing 0.1 M of HC2H3O2 is around 2.88.

This is a Neutralization reaction. HBr(aq)+CsOH(aq)--->CsBr(aq)+H2O(l)
