Precipitation Processes01:12

Precipitation Processes

574
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Precipitation and Co-precipitation01:17

Precipitation and Co-precipitation

2.0K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Precipitation Gravimetry

7.1K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Types of Coprecipitation01:10

Types of Coprecipitation

824
Coprecipitation is the contamination of a precipitate by otherwise soluble species and occurs via different processes. In colloidal precipitates, coprecipitation occurs via surface adsorption. For instance, barium sulfate has a primary layer of adsorbed barium ions and a secondary layer of nitrate counterions. This results in contamination of the precipitate by barium nitrate.
Sometimes, ions in a crystal lattice can undergo isomorphous replacement by inclusions of similar charge and size. For...

Precipitation Titration Curve: Analysis01:21

Precipitation Titration Curve: Analysis

1.2K
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...

Precipitation Titration: Overview01:26

Precipitation Titration: Overview

6.8K
Precipitation titration involves the reaction of a titrant and an analyte to generate an insoluble precipitate. While precipitation titration uses various precipitating agents, silver nitrate is the most common precipitating reagent; titrations involving Ag+ are called argentometric titrations. Usually, the endpoint in a precipitation titration can be detected by visual indicators.
A precipitation titration curve demonstrates the change in concentration of the titrant or analyte upon adding the...

Area of Science:

  • Atmospheric Science
  • Cloud Physics
  • Climate Modeling

Background:

  • Marine low clouds play a critical role in Earth's energy budget.
  • Accurate representation of cloud microphysics is crucial for climate model projections.
  • Understanding precipitation formation in these clouds is a persistent challenge.

Purpose of the Study:

  • To develop a parameterization scheme quantifying the influence of liquid water path (LWP) and cloud droplet number concentration (CDNC) on precipitation probability (PoP).
  • To investigate the spatial-temporal variations of PoP in tropical marine low clouds using combined satellite data.
  • To diagnose the root causes of warm rain biases in global climate models.

Main Methods:

  • Combined measurements from Moderate Resolution Imaging Spectroradiometer (MODIS) and CloudSat radar.
  • Developed a bivariate probability of precipitation (PoP) function based on LWP and CDNC.
  • Conducted sensitivity tests using the developed parameterization scheme.

Main Results:

  • Spatial-temporal variations in grid-mean in-cloud are largely explained by the joint probability density function of LWP and CDNC.
  • Stratocumulus to cumulus transitions in the Southeastern Pacific and Atlantic are primarily driven by CDNC variations.
  • The annual cycle of is mainly influenced by LWP variations.

Conclusions:

  • The developed parameterization scheme effectively quantifies microphysical controls on precipitation probability.
  • Identified distinct roles of CDNC and LWP in driving precipitation changes in marine low clouds.
  • Provides a viable method for diagnosing and improving warm rain parameterizations in climate models.
