Precipitation Gravimetry01:03

Precipitation Gravimetry

7.0K
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...

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Precipitation and Co-precipitation

1.9K
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 Processes

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 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: Endpoint Detection Methods

2.0K
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3.
In the Volhard method, a standard excess of AgNO3 is first added to the...

Summary

Drought monitoring in India reveals significant terrestrial water storage depletion, particularly in the Indo-Gangetic plains. GRACE-Drought Severity Index (GRACE-DSI) data indicates more widespread drought impacts than precipitation-based indices.

Area of Science:

  • Hydrology
  • Climate Science
  • Environmental Monitoring

Background:

  • Drought poses a significant threat to water resources, agriculture, and socio-economic development.
  • Effective drought characterization and monitoring are essential for impact mitigation.
  • Spatiotemporal drought assessment using terrestrial water storage at the sub-basin scale in India remains underexplored.

Purpose of the Study:

  • To characterize and monitor drought propagation across Indian sub-basins using terrestrial water storage anomalies (TWSA).
  • To compare drought indices derived from TWSA and precipitation data for a comprehensive assessment.

Main Methods:

  • Utilized Terrestrial Water Storage anomalies (TWSA) from the Gravity Recovery and Climate Experiment (GRACE) satellite data.
  • Employed precipitation data alongside TWSA to compute the Combined Climatological Deviation Index (CCDI).
  • Calculated the GRACE-Drought Severity Index (GRACE-DSI) solely based on TWSA data for comparative analysis.

Main Results:

  • GRACE-DSI showed more significant negative trends across Indian sub-basins than CCDI, indicating widespread depletion of terrestrial water storage (TWS).
  • The Indo-Gangetic plains experienced multiple drought events between 2002-2017.
  • North Ladakh recorded the longest drought duration (26 months) and highest severity (-44.2835) by GRACE-DSI, while Shyok sub-basin showed 17 months duration and -13.4392 severity by CCDI.

Conclusions:

  • Terrestrial water storage depletion is a primary driver of drought in most Indian sub-basins.
  • GRACE-DSI is a valuable tool for identifying drought events driven by TWS loss.
  • The study highlights the need for integrated drought monitoring systems considering both precipitation and TWS.
